F$PID() is a lexical function that returns a process identification number and updates the context symbol to point to the current position in the system's process list.

Syntax

F$PID(context-symbol)

context-symbol is an arbitrary symbol established with a call to F$CONTEXT.

Examples

$ CONTEXT = ""
$ START:
$     PID = F$PID(CONTEXT)
