The Question is:
I have code (Fortran) that calls LIB$SPAWN to execute a DCL command procedure.
I realize that if the command were put into a batch queue via a submit, I
wouldn't have the current problem, but I need to have the command processed
before anything else happ
ens. The actual command is:
LIB$SPAWN -
($@MM$MADATA:FTP_DELLINE/OUT=FTP_DELLINE.LOG)
The problem we have is that expected warning messages are printing to the users
screen as well as to the log file. Would it work to assign sys$error to the
null terminal? Or does that have inherent problems?
The Answer is :
You will want to consider use of sys$sndjbc[w] in place of the
current lib$spawn if you wish to issue a SUBMIT operation.
If you wish to pursue the current implementation, use the
optional output and error arguments on the lib$spawn call,
or recode the DCL procedure to use I/O redirection (your
OpenVMS version is sufficiently ancient that it lacks the
DCL command PIPE, a command which makes DCL I/O redirection
rather easier), or use the /ERROR qualifier available with
the command procedure invocation.
The COPY/FTP command may be of interest, as well.
