2. If there is no EXEC file, DMSINT executes SVC 202, passing the
scanned parameter list, with the command name in the first eight
bytes. DMSITS will perfor. the search described for SVC 202 in an
effort to execute the command. If DMSITS returns to DMSINT with a return code of -3, indicating
that the search was unsuccessful, then DMSINT uses the CP DIAGNOSE facility to attempt to execute the command as a CP command.
4. If all of these searches fail, then DMSINT displays the error
message UNKNOWN CP/CMS COMMAND. See Figure 28 for a description of this search for a command name. 260 IBM VM/370 System programmer's Guide
