QuickBasic 4.0

Microsoft QuickBasic, not to be confused with the lesser QBasic, was a Basic interpreter and compiler product loosely based on GW-Basic. Version 2.0 for DOS and later included an Integrated Development Environment. Microsoft also produced QuickPascal and QuickC with similar integrated environments.

QuickBASIC was positioned as an entry level for their BASIC Professional Development System, and competed against language products targeted at hobbyists, such as those from Borland.

Wanted: Manual scans.
