OpenStreetCode

OpenStreetCode is an esolang by User:PythonshellDebugwindow based on JOSM, an editor for OpenStreetMap.
==Syntax==
OpenStreetCode files are .OSM files (generatable using JOSM). All valid .OSM files are valid OpenStreetCode files, syntax-wise at least.
==Memory==
OpenStreetCode uses an unbounded signed integer cell index, an unbounded array of unbounded signed float cells, and an unbounded signed incrementation register.
==Use of elements==
Note: all elements can have other, unnecessary tags (name=*, landuse=*, shop=clothes, etc.); these do not affect the program in any way.
===Nodes===
Nodes represent the instructions in a program. All nodes must be connected to ways.
====Instruction table====
Tag 	Instruction
amenity=bank 	Add 0.1 to the incrementation register
amenity=bureau_de_change	Subtract 0.1 from the incrementation register
amenity=atm 	Add the incrementation register to the cell at the current cell index
craft=beekeeper 	Increase the current cell index by 1
craft=plumber 	Decrease the current cell index by 1
shop=wine 	Print the cell at the current cell index as a character
shop=copyshop 	Print the cell at the current cell index as a float followed by a newline
craft=photographer 	Input a character to the cell at the current cell index
shop=painter 	Input a float to the cell at the current cell index (invalid floats are treated as zero, valid floats match the regex [+-]?[0-9]+(\.[0-9]+)?)
===Ways===
Ways are used to connect nodes. Ways must have the highway=residential tag.
===Relations===
Relations are used for loops. type=multipolygon relations represent while loops, with role=outer ways being "inside" the while loop, role=label nodes representing the entry points of loops, and role=admin_centre nodes representing the exit points of loops (these loop relations should contain have exactly 1 label and admin_centre and at least one outer); these should be closed, and their labels and admin_centres should each be a part of at least one outer way. These loops start at the label, jump to the admin_centre if the cell at the current cell index is equal to zero; otherwise they follow the outer way(s) to the admin_centre, jump back to the label if the cell at the current cell is not equal to zero, follow the outer way(s) to the admin_centre, conditionally jump back again, and so on; basically, your traditional while loop.
==Examples==
===Print the letter A===
====Image====
====Text====
To view this code in JOSM, simply copy it into a .OSM file on your computer, launch JOSM, and open the file you created.
