- It's interesting to see how a product can evolve!
-
- Version 2, Release 2 of IBM's VS FORTRAN Program Product (June 1987)
- added support for 31-character symbolic names, which can include
- the underscore (_) character.
- Version 2, Release 3 (March 1989) added comments-on-the-same-line,
- DO WHILE, and ENDDO.
- Version 2, Release 4 (August 1989) added graphic relational operators.
- Version 2, Release 5 (September 1991) added the use of TAB characters
- in source programs, and coding of indirectly-recursive FORTRAN routines.
-
- I've omitted many other additions and performance enhancers (striped I/O,
- multi-tasking, parallel-processing, and vector-support, etc.).
