Remember that TheBob did his programs in QuickBASIC or QBasic which didn't have "_PUTIMAGE" and other commands you're seeing in QB64(PE). Must put "(PE)" in parenthesis although I don't like it, but I mean the "qb64-dot-com" version as well as Phoenix Edition of QB64. Remotely, also the old "Galleondragon" version and a few others.
The empty parenthesis shouldn't be necessary in "PUT" clause. Probably Q(uick)BASIC didn't like it.
Maybe TheBob chose some file suffixes "carelessly", ie. there was no way for him to know which application supported which file suffix. Like years ago I came across a program that saved in WRK format, while that was something recognizable by Cakewalk music software a long time ago, and if I'm not mistaken was also the first Lotus123 file format. No I am mistaken for the latter it was "WKS", but "WRK" was used by some other commercial app for Windows.
EDIT: That "DWG" file is actually a sprite created by another program written by TheBob. He didn't feel like doing like "Kong" program, creating another program just to draw the screen elements and expecting the user to run it only to get sprites for the game.
EDIT 2: I think TheBob would be pretty frustrated with QB64 if he wanted to get away from "DIM", "GET" and "PUT" to deal with sprites. Instead of inefficiently creating an array for a sprite, just load it from a file and it's identified only with a long-integer variable. Much simpler. No need to codify with text files and other such business. It even supports graphics modes beyond capabilities of "SCREEN 13".
If you downloaded the "three-dee world game" that MasterGy came up with you should see several directories sprinkled with text files. The contents are somewhat random, according to the purposes of the components of his program. TheBob actually did the same thing with some of the text files. Otherwise a few binary files were created which should be graphic sprites.
