BASICA (short for "
Advanced BASIC") is a simple disk-based BASIC interpreter written by Micro$oft for PC-DOS. BASICA allows use of the ROM-resident BASIC included with early models of IBM's PC while DOS is loaded (the ROM BASIC itself runs when nothing is loaded when booting) and adds functionality such as file access and storage of programs on disk. It does not run on non-IBM PCs and even on later IBM models, since those lack the requisite ROM BASIC.Later versions :
Qbasic and Visual Basicwhich both inherited its syntax...
