Help on creating a "3D"ish game (char[] to DATALONG)

[AdeO]

Hi, my goal is a game like Battlezone for Atari 2600, but with the T-14 Armata, and I would like to know if there is a simple way to create tiles from char, like:

DIM oneLineRepeat AS STRING = "00F1C00"
my_tile:
DATALONG $oneLineRepeat
DATALONG $oneLineRepeat
DATALONG $oneLineRepeat
DATALONG $oneLineRepeat
DATALONG $oneLineRepeat
DATALONG $oneLineRepeat
DATALONG $oneLineRepeat
DATALONG $oneLineRepeat

And also, whats the best way to concat strings with BEX?
Thank you in advanced!

Problem partially solved so far...

There's no better way to concat than:

string_concat$ = string1$+ string2$

But after making several functions, I still can't return a valid long for the labels.
And as long hex$() doesn't help me with VdpRamRead(<even_address>), I made my own a function that will return only a 4 bytes long hex, like the C "%.4X", I hope it may help someone in the future:
(For some reason, include don't work always, so copy and paste at the end of your code COMPLETELLY IGNORE THAT "copyright" thing, it's my craze, I do that on "autopilot")
