# Z80 Assembly/What You Need

To begin programming, you will require the following.
* Calculator: a TI-82, TI-83x, TI-84x, TI-85, or TI-86 or newer model.
* TASM: This program "assembles" the assembly code you will write to code that the computer understands.
* TI-83 Plus Include File: this text file assists TASM by giving it necessary information when assembling.
* DevPac8x: this program changes the code that TASM has assembled into a file that you can transfer to your calculator.
* TI SDK: also known as the TI 83 Plus Flash Debugger, this program allows programs to be tested on the computer for errors without having to transfer them to the calculator.
* Link: this will allow you to transfer your programs to the calculator from the computer.
Now that you have everything, you will need to set up the environment so that everything works together. It is highly advisable to follow examples given.
* Make a folder where you will put all of your Assembly files (e.g. C:\ASM).
* Unzip the TASM files into a subfolder of ASM titled 'TASM' (e.g. C:\ASM\TASM).
* Put 'ti83plus.inc' into your TASM folder.
* Unzip the DevPac8x files into a subfolder of ASM titled 'devpac8x' (e.g. C:\ASM\devpac8x).
* Make another subfolder of ASM titled 'Programs' (e.g. C:\ASM\Programs). This folder will be where all of your programs will be placed.
* Install the TI SDK.
* Open Notepad and type the following:
Save this as 'compile.bat' into your Programs folder. Make sure to set 'Save as type:' to 'All files' or it will save as 'compile.bat.txt'.
Now, just verify that you know how to use the link and turn on your calculator.
# Z80 Assembly/Z80 Architecture

The Z80 architecture is based on that of the Intel 8080.

## Registers

The Z80 has eight main registers, six of which are paired to form three 16-bit general-purpose registers.
* A (accumulator) is the main 8-bit general-purpose register.
* F (flags) stores flags used to control the flow of a program that are set based on the last arithmetic instruction:
** Bit 7 (S; sign bit) indicates whether the result was negative.
** Bit 6 (Z; zero bit) indicates whether the result was zero.
** Bit 4 (H; half-carry bit) indicates whether the result required a carry from a lower to an upper nybble.
** Bit 2 (P; parity bit) indicates the parity of the result.
** Bit 1 (N; subtraction bit) indicates whether the operation was a subtraction.
** Bit 0 (C; carry bit) indicates whether a carry occurred.
* BC is a 16-bit register, made up of B (most significant byte) and C (least significant byte).
* DE is a 16-bit register, made up of D (most significant byte) and E (least significant byte).
* HL is a 16-bit register, made up of H (most significant byte) and L (least significant byte). HL is generally used for addressing locations in memory, as there are a number of instructions that use HL for this purpose that don't have counterparts for BC and DE.
Each of these main registers has a shadow register counterpart. These registers are accessed by swapping with the main registers using the EX and EXX instructions. EX can be used to swap A and F with their shadow counterparts A' and F', while EXX swaps the three pairs BC, DE, HL with their counterparts BC', DE', HL'.
In addition to the 8-bit registers there are a number of special 16-bit registers:
* IX and IY are the index registers, designed to be used as base offsets for addressing memory.
* PC is the program counter, indicating the location of the currently executing instruction.
* SP is the stack pointer, indicating the location of the top of the processor stack.

# United States Postage Meter Stamp Catalog/Sub-group PD-G – Digital label with "POSTAGE DUE" across top, Intermec
#### Sub-group PD-G: Digital label with "POSTAGE DUE" across top, Intermec

* The Intermec Postage Validation Imprinter trial that took place in the late 1980s produced Postage Due stamps in addition to postage.
Type PDX-A1A in the 2001 edition
PD-G1. Intermec (digital), January to March 1986. [RRRR]
    From the same system that produced Type PO-B5.2 but instead of an eagle design the stamp has large negative "POSTAGE DUE" across the top.
    Four machines (000009, 000010, 000011, and 000012) were used in Vienna Virginia (VIENNA / VA). Postage Due stamps have been seen or reported only from 000011 and 000012.
    V/F: Ø.ØØ
NOTES:
* Postage Due stamps from machines 000009 and 000010 may exist but have not been seen by or reported to us.
* These stamps are known only a mint tapes sold to collectors. No covers properly franked by this stamp are known to exist.
* Presumably a Postage Due version of Type PO-B5.1 was in use from July 31, 1985 to the end of that year, but no examples have been reported.
Type PDX-A1B in the 2001 edition
PD-G2. Intermec (digital), March 1986. [R-RRR]
    As Type PO-B5.3 but instead of an eagle design the stamp has large negative "POSTAGE DUE" across the top.
    It is safe to assume that each machine described for Type PO-B5.3 was able to produce Postage Due stamps. Listed below are those seen or reported:
       A. Used in Vienna, Virginia with town mark:
          - Vienna / VA : I8600101
          - VIENNA / VA : I8600155, -156, -157, -158
       B. Used in Tampa, Florida:
          - TAMPA / FL PO 33630 : I8600115, -120, -123, -130, -163, -176, -180
          - TAMPA / FL PO 33629 : I8600122, -127, -148, -177, -178
       C. Used in Saint Petersburg, Florida:
          - SAINT PETE / FL PO 33730 : 18600136, -140, -150, -152, -165, -175
          - Saint Pete / FL PO 33730 : I8600186
          - SAINT PETE / FL 33730 : I8600277
          - ST PETE / FL 33730 : I8600152, -165
          - St. Peteburg / Fl 33730 : I8600123
       D. Used in Clearwater, Florida:
          - CLEARWATER / FL PO 33575 : I8600106, -129, -141, -276
          - CLEARWATER / FL. 33575 : I8600160

       F. Used in Washington DC: WASHINGTON / DC 20016 : I8600192, -206 [RRR]
    V/F: Ø.ØØ
NOTES:
* The early labels used in Vienna, Virginia did not have anti-peel slits. Starting in late 1986 or early 1987 labels with anti-peel slits cut into the edges came into use. All stamps from the other locations were printed only on labels with anti-peel slits. The Vienna stamps without the anti-peel slits are relatively scarce.
* Nearly all these Intermec Postage Due stamps available are mint tapes sold to collectors. Just a handful of covers franked by this stamp are known to exist.
# United States Postage Meter Stamp Catalog/Sub-group PD-H – Digital P.O. counter label with "PD" in town line, MOS-UNISYS
#### Sub-group PD-H: Digital P.O. counter label with "PD" in town line, MOS-UNISYS

* Although not intended for collecting Postage Due, the MOS/UNISYS Postage Validation Imprinter system was used occasionally for that purpose in some post offices. Only one such machine is known to have been specifically labels as a Postage Due franker.
Unlisted in the 2001 edition
PD-H1. MOS Corporation/UNISYS (digital). [RRRR]
    Type PO-B6.1 with town line "TAMPA PD BR.FL" .
    At least one of the PVI machines used in Tampa, Florida has "PD BR" (for Postage Due Branch) in the town line. Although other PO-B6 type PVI stamps have been used to collect postage due, the Tampa example is the only one known dedicated to collecting postage due and indicating so in the town line.
    V/F: $0.00 $00.00
NOTE: A similar Postage Due stamp based on Type PO-B6.4 may exist but has not yet been reported.

## Overview

ODBC is the acronym for the oft used API Open Database Connectivity. Many applications and application programmers use ODBC in order to access relational databases, such as SQL and Microsoft Access, and to manipulate the data within the databases. Specifically, JDBC (Java Database Connectivity), which is based on ODBC, is the API used by applications developed in Java to perform these various tasks. Moreover, JDBC is now capable of handling advanced datatypes in SQL which in turn becomes useful when dealing with XML. Also, JDBC has within it the ability to actually create XML data. Furthermore, the use of JAXP (Java API for XML Processing) along with JDBC provides yet another way of manipulating and using relational databases and XML. In any event, there are multiple ways to use the JDBC API with XML.

## JDBC and XML Documents

Many Java Applications written today will more than likely interact with an SQL database (or a relational database, but for the sake of uniformity, we will work with SQL.) Depending on the intent of the application, there may be the case of actually storing an XML document for display or for manipulation. Whatever the case, JDBC now supports all datatypes defined in the SQL:1999 specification. One of theses datatypes is the CLOB (character large object) datatype. This datatype is perfect for storing XML documents. This is one way XML and the JDBC API works with each other.

## JDBC and XML Production

One of the more interesting things about JDBC is that it can be used to gather MetaData. Meta-data is nothing more than data about data. From an XML standpoint, this is very useful because we can create XML data on the fly with nothing more than a table name. The class that makes this possible is java.sql.ResultSetMetaData. Consequently this class is a part of the JDBC API.

## JDBC and JAXP

Another intriguing way of dealing with XML objects is within the JAXP (Java API for XML Processing). JAXP and JDBC together provide an infrastructure for developing applications using XML and SQL.
Whenever XML instances in applications are dealt with, an XML parser is a good tool to use. The XML parser turns the XML document into an object or something the application can uses. Specifically, Document Object Model (DOM) takes and XML instance and converts it into a tree. This specific parser can be found in the JAXP API. You may then store the parsed object in an SQL database for future use. This may open up many ideas of how one may use JAXP and JDBC together when an issue presents itself of dealing with XML and SQL.
