It offered full compatibility with BASICA/GWBASIC. It was a major release. Comes with QB.EXE and QB87.EXE, giving QuickBasic both a compiler and an interpreter for quick testing turn around. The QB87.EXE program supports the math coprocessor. The editor is significantly improved over 2.0. The following additional new language statements are added: SELECT CASE, DO LOOP, CONST. It includes partial support for SUBs, but all variables defined inside are STATIC (you have to create your SUBs using SUB name (parameters) STATIC for forwards compatibility, nice take). The editor includes insert/overtype mode command. You can use the editor with SuperKey, Prokey, or Sidekick. Other features include a simple debugger to set breakpoints and watch variables. The editor can take advantage of 43-line mode on the Enhanced Graphics Adapter (EGA) card.
