ASIC is a compiler and integrated development environment for a subset of the BASIC programming language. It was released for MS-DOS and compatible systems as shareware. Written by Dave Visti of 80/20 Software, it was one of the few BASIC compilers legally available for download from BBSes. ASIC allows compiling to an EXE or COM file. A COM file for Hello world program is 360 bytes.
ASIC has little or no support for logical operators, control structures, and floating-point arithmetic. These shortcomings resulted in the tongue-in-cheek motto, "ASIC: It's almost BASIC!"
