The Question is: Is there a fortran to C header file converter for OpenVMS. I can only find tools for unix ie. f2c. I have written my own converter, however I would be interested in comparing it to an existing version. What would be nice would be C code I could compile and run on the alpha. Alternatively, would it be feasible to port f2c to OpenVMS. Regards, David Crook The Answer is :
The OpenVMS SDL tool (available on the OpenVMS Freeware) will provide
language-specific include files from a language-independent definition
file. Back-ends are available for C, Fortran, Bliss, Ada, PL/I, SDML
and other languages. SDL documentation is included on the Freeware.
Also available on the OpenVMS Freeware is the GNM tool, which permits
the creation of a common set of files for the error messages and the
recovery, files which are then converted into documentation (in SDML
format accepted as input by the DOCUMENT package) and an equivilent
message definition file (in the MSG format accepted as input by the
OpenVMS MESSAGE compiler).
The OpenVMS MESSAGE compiler also provides the (undocumented) /SDL
switch, which causes the MESSAGE compiler to generate an SDL-format
output file based on the MSG file input. This output file can then
be converted into the necessary language-specific include files using
the aforementioned SDL compiler.
To get the 64-bit format _NEW_STARLET files used on OpenVMS Alpha,
typically commands such as the following SDL commands are used:
SDL/ALPHA/VMS_DEVELOPMENT/C_DEVELOPMENT/LANGUAGE=...
SDL/VAX/VMS_DEVELOPMENT/C_DEVELOPMENT/LANGUAGE=...
The OpenVMS Wizard would expect that the f2c code could be ported to
OpenVMS. Not having looked at the f2c code, the OpenVMS Wizard cannot
make that statement with any degree of certainty. (Obviously, someone
may well have already ported f2c to OpenVMS.)
