Forum Post: RE: Problem calling C program

$

I'm using gcc on the AIX machine for C compilations - we don't have IBM's cc and given that we have the grand total of one C program, it's not very likely that we'll be getting it. The programs compile successfully as per original versions, though I have made two minor changes to testc - null byte to terminate ws-name and "by reference" in the call to helloworld. helloworld works quite happily when invoked standalone. I tried putting in an additional call to sprintf this in working-storage       01  ws-to-buff                  pic x(80).       01  ws-line-desc.           03  filler                  value "Buffer says hello %s". and this in procedure division           call "sprintf"              using by reference ws-to-buff                                             by reference ws-line-desc                                             by reference ws-name           display ws-to-buff and this works. So is it an incompatibility with gcc?
