User interrupt handling

The HLC function library contains an interrupt-handling function, prockint(), that allows you to check when a user presses the STOP key (CONTROL-C on UNIX; CONTROL-BREAK in Windows).

Use prockint() in place of your own interrupt-handling function. Using your own interrupt-handling function during an HLC call could interfere with how Progress handles interrupts once you return from the call.
