I wrote a VMS F77 to Ansi F77 a few years back. It was not an easy task. To
process all of the extensions (records, structures, RMS IO, etc) it wound up
being a very complex project. Sometimes the extensions will require several
lines of F77 code, and/or function and subroutine calls. This can lead to
problems with IF statements and other function calls. Simple conversion of
octal constants, in-line comments and such can usually be done with lex.
Just remember:
IF(IF(1).ne.10) IF(IF(3)+3)=3
