GOAL:
How to make 4GL to error out if no program running on the other end of a pipe created with mkfifo?
FACT(s) (Environment):
UNIX
FIX:
4GL does not error out when sending data to a pipe and there is no program
at the other end of the pipe.
The alternatives are:
- use OUTPUT THROUGH statement which will start the other job and automatically creates a pipe to send data
- send data to a file with OUTPUT TO statement, the other end program picks data whenever it runs
