While on the subject of C and FORTRAN on VMS ... How does one pass strings between the two compilers??? We have VAX FORTRAN and GnuC compilers. I just cannot pass any strings between a C routine and a FORTRAN routine. Thanks in advance for any help.

The problem is that FORTRAN programs use the CLASS_S descriptor mechanism while C modules have zero terminated strings by default. The best way to solve your problem is described in chapter "Using VAX C Features on VMS" of "Guide to VAX C" manual. It describes how function parameters must be declared to be conformant to the CLASS_S descriptor class. The only problem in doing this is that ALL the modules calling the C routine MUST have their parameters defined as CLASS_C descriptor, otherwise... Roberto Divia` =============
