CALL/360:BASIC is an IBM dialect of the BASIC programming language for the System/360 and later platforms. It was based on mid-1960s versions of Dartmouth BASIC but added a number of extensions. Most of these were related to file handling, which, at that time, Dartmouth lacked. It also added support for the mathematical symbols found on some IBM terminals, so that could be entered directly as . Differences are otherwise minor.

Differences are otherwise minor. ==History== CALL/360:BASIC was announced in 1968, along with several other languages for the system including APL and FORTRAN and the Datatext markup language based text editor. Early advertizing for the system boasted that one could "Start learning CALL / 360 : BASIC after breakfast and you can share our computer before lunch". The CALL/360 suite was developed within IBM's Information Marketing department. Initially, the products were considered proprietary and could only be accessed via the online service. Customer demand forced them to offer these products to other System/360 users, which they did by releasing it on an "as is" basis with no support. Later the same year, IBM transferred this department, along with the rest of its timesharing services, to the Service Bureau Corporation (SBC), including the CALL/360 operating system (later known as CALL/OS) and CALL/360:BASIC. Manuals after that date refer to the language as an SBC product. In 1973, SBC was itself transferred to Control Data Corporation as part of a long running anti-trust lawsuit. ===Citations=== ===Bibliography===
