Mixed-Language Programming, MMS, LINK/OPTION?

» close window

The Question is:

 
I can't find any documentation that shows how to link a COBOL program with a C
 module using MMS.  It works fine otherwise.
 
Here's what I'm doing now, not in MMS -
 
   $LINK MAINPROG,CPROG,SYS$INPUT/OPT
SYS$LIBRARY:VAXCRTL/SHARE
 
Then I add a $SHOW TIME command because it seems to wait for the next command.
 
Can you provide any information?

The Answer is :

 
  Please specify an options file, rather than attempting SYS$INPUT:.
 
  Documentation on mixed language programming is included in the OpenVMS
  Calling Standard documentation.  You will also need to address any
  language-specific compilation (eg: For Compaq C, also please see the
  FAQ) and linking required, this for individual components and for
  the aggregate image.  C, for instance, can require its Run-Time Library
  (RTL) be initialized via a VAXC$CRTL_INIT call when the main routine
  for the image is not written in C.
 
  If the OpenVMS Wizard has guessed correctly on the version of the C
  compiler in use here, the version V3.2 of the VAX C compiler in use
  has turned ten years old circa January 2001.  You might consider an
  upgrade to a more recent compiler version.
