- WFP is short for 'WaitForPort', a program that waits for a named port the
- stated number of seconds. If 'seconds' is zero the program simply checks
- for the existence of the port and exits.
-
- When the port is created within the allocated time, the program returns OK,
- otherwise it returns WARN (error code 5).
-
- Use this program to wait for a ARexx host to come up.
-
- Example:
-
- Run ZVT
- WFP ZVT.1 30
- if warn
- echo "ZVT did not start"
- quit
- else
- rx "address zvt.1;hide;receiveron"
- endif
-
- Tries to start ZVT and switches it into answer mode if it gets started
- within thirty seconds.
