assistant: Weary from translating the works of Stephen King into Latin, Bob said:
    In this case, Quintin is correct, and you are not.  A
 fixed-length string variable, whether DIMmed or TYPEd, will
 always be that length and padded on the right with nulls.
 Therefore, while rtrim$ will strip the nulls out of a
 fixed-length string, if you place the results back into a
 fixed-length string, that will then be padded on the right
 with nulls.  So, the following code:
 dim c as string * 10
 c = "12345"
 print "[" + c + "]"
 c = rtrim$(c)
 print "[" + c + "]"
 c = rtrim$(c, chr$(0))
 print "[" + c + "]"
 b$ = rtrim$(c, chr$(0))
 print "[" + b$ + "]"
 ...produces the following screen output:
 [12345     ]
 [12345     ]
 [12345     ]
 [12345]
    The first line is the original contents of c, padded onm
 the right with nulls.  The second line is the contents of c
 after a regular rtrim$ using the default of only stripping
 spaces.  As you said, the nulls are still there.  The third
 line shows your error, in that, while rtrim$ did its job of
 stripping the nulls, PowerBASIC then put the resuling
 5-character string back into a 10-character-length
 fixed-length string, and padded it with nulls.  The fourth
 result is what you expected to happen, i.e., the result of
 rtrim$ was placed into a variable-length string, which
 doesn't put the nulls in.

assistant: Yes, this has been discussed.  What you (and everyone else in this echo,
from what I've seen so far) keep forgetting is the original user in
the original message was defining one structure, then mapping it
to another variable.  And, the structure was reading data which earlier
was mapped as nulls by the program which created that data.
In other words, we really are all right (you, me, others) except for
the original user who misunderstood how the original data was created.
We ALL learned something here.  Maybe a few things...
* It's a waste to define a variable in a structure then copy it to another
  variable.
* Null data exists in most (if not nearly all) other data structures
  dynamically created by programs compiled in formats other than basic,
  as the padding character.  Local variables, and copied dimensioned
  ones mapping to the original, can be allocated with spaces.
So, I don't disagree with ya.  I just answered according to a *specific*
problem, and you guys are supplying excellent facts in a general sense.

But it should be possible to enhance the IDE a lot... it's nice to have that
good features PB provides but on the other hand it's not that much fun
working within the IDE as it was with the QB-Ide...
I plan to write some kind of enhanced IDE for PB but that project will have
to wait since I have not that much time I'd like to have for programming...
:-/
Why not writing it yourself? I think that the format of PBs help files isn't
top secret, so why not asking Bob Zale to leave the documentation for those
files in order to develop such a tsr?

Hello Tim !!
The difference is, 't.Str' is a 'Fixed lenght string' and not a 'Dynamic
String'. What I mean, for a 'Dynamic String' do you need a string handle
on the parameter stack, but not for a 'Fixed lenght String'.

Yeah i already made it, and had a bit of a go myself, with some help from the

Oh, so yeah, ya use the staus register to get it..  I was trying to use the

in from tghe output one. hhe.  Stoopid me. :)
    Well, its made it a little but clearer on how it sorta works.  But to
ell
ya the truth, its still over the top for me. heh.  I'l work her out. Yeah, ..
Well, i would use the serial port but, they were being used.  Otherwise i
would have used them, as they are HEAPS easier. ehhe :).   ThanX for ya help

Write your reply.

assistant: It works here.  And PowerBasic does not have an error that says 'does
not work'.
In the example you gave, t is a 15-byte fixed-length string, so why
in the world would you tell the SUB it is a user-defined type?  The SUB
statement is where you tell the subroutine what kind of variable you
will pass it.  The error 481 you got is telling you that you are trying
to pass a different kind of variable than you said you would.
You gave two variations, A and B.  in B, you tell the sub to expect a
variable-length string but try to pass it a fixed-length string.  That
causes an error 481/parameter mismatch.  In A, you convert the
fixed-length string to a variable-length string, call the sub, and
convert the value it returns back to fixed length.  That, naturally,
works.  (And if you want to use that subroutine for strings with a
length of other than 15 bytes, might be a better way to do it anyway).
BTW, your example has two different variables called t.  One is of a
user-defined type in the main level, the other is a variable-length
string in the subroutine.  Don't confuse them.

I grabbed several pages off a German web site. I didn't find any help
on the IDE issue. In fact it appears that this feature common to QBs
editor doesn't exist. So, I programmed QEdit to work for me, and I
don't use the IDE at all. I don't have the context sensitive helps,
however. I have to look up the error in the manuals.

assistant: Greetings All,
I am still using QB45 and need to know how to check for the existance of a
file.. other than being sloppy and using something like:
ChkFile:
OPEN "Filename" FOR APPEND AS #1
If LOF(1) = 0 THEN
GoTo NoFile
End If
Print #1, A$
Close #1
Return
NoFile:
Close #1
Goto Label
This example is goofy coding but I just want to know if there is something in
QB like: If Exists(Filename) GOSUB FoundIt ... I am writting a BBS Chat Door
and need a quick way for testing for a given filename... I have found
something like this in QB but it seems to work backwards and/or not always
consistant :-/
BTW - Thanks to those that helped me with the LORD IGM structs..Got it
working and just waiting for Seth Able's seal of approval before releasing it

Write your reply.

assistant: Yes, you can address each data line individually.  There are also some
open collector outputs that are addressable on another register, but
don't think they could handle the current of a relay.  I have only
worked with mechanical type relays, and typically just build a
Darlington amp out of a couple npn transistors to drive the relay.  You
can also use the chips like ULN2003 for this purpose.  I don't see why
you couldn't use the same technique to drive a solid state relay.  I
use the parallel port on my bbs computer to control an AC outlet box I
made and it works great.  I also made a stepper motor controller
circuit for a class one time (before discovering the UCN5804B chip) and
controlled it with parallel port.  Its a good source of digital i/o
lines.  Do you have access to the web?  There is a good faq on parallel
ports on one site, I'll write it down and post it, or you could email
me at hbcsc388@huey.csun.edu and I'll attach it back to you.     Eric

Write your reply.

assistant: NO, NO! Don't say that!!! I pass TYPED records all the time. And, I
need to be able to modify them from within the SUB.
For instance - I have several subs like the following:
SUB BitCode (i%, b%, w%, s%)
    i% = (i% + s% * 2 ^ b%) AND (w% * 2 ^ b%) OR (i% AND NOT (w% * 2 ^ b%))
END SUB
(I'll convert to ASM, once I figure out how pass the TYPE record)
The above is called like this:
    BitCode rec.PDate, 11, 3, 1
This works fine with QuickBASIC, but not PowerBASIC.
I find it hard to believe that the programmers at PowerBASIC didn't
make some sort of provision to accomodate this.<sigh>
That will not work in all instances where I need to modify the
element. What do I do in the above case.

passing of records for modification defined in a TYPE???
What do I need do to to reference the element *and* make
modifications to it from within a SUB? QuickBASIC doesn't have this
problem, frankly I am suprised that PowerBASIC can't deal with
this.<bummer>
The only way around this is to jocky the pointer as in the following:
x$ = t.str
SUB x$
t.str = x$
There's got to be a more elegant way.
Isn't there?
