Programming in GW-BASIC
Every computer in the 1980s and into the 1990s had some kind of BASIC programming environment. The BASIC on the first IBM PC was BASICA, which required a BASIC ROM. After that, Microsoft released GW-BASIC, which didn't require BASIC in ROM. GW-BASIC was the default BASIC in MS-DOS until MS-DOS 5, when they replaced it with QBASIC.
In May 2020, Microsoft released the GW-BASIC source code under the MIT license, and FreeDOS developers have been getting that code to assemble using modern tools. They recently released a new version, so let's explore GW-BASIC on FreeDOS.
