I started programming in BASIC on a Tandy Color Computer 2 in junior high school when I was 12 years old. I've since tried other languages but have always come back to BASIC because of its simplicity, compactness, and ease of use. I discovered Marin Saric's METAL BASIC compiler for Mac OS 9 and Mac OS X in 2002 and have been using it ever since.
METAL_OSX.zip and METAL_OS9.sit are archives that includes the METAL 1.7.3 BASIC compiler & documentation, the source code for all the programs you see below, and the screen captures as well. Filesize ≈ 17 MB
