Discussion
The XCALL statement transfers control to an external subroutine or user-defined function. (It cannot be used to call system-supplied functions.) Upon return from the subroutine or function, control is transferred to the statement following the XCALL statement.
Any ONERROR traps set in the calling program are disabled while the external subroutine is being processed. Once control returns to the calling program, the error traps are re-enabled. |
