ARITRAP

Syntax

           I*V
  ARITRAP (trapstate);

Parameters

trapstate

(NM) 32-bit signed integer by value (required)

(CM) 16-bit signed integer by value (required)

(NM) Enables/disables arithmetic traps:

Value	Meaning
0	Disable all arithmetic traps
1	Enable all arithmetic traps (except the IEEE inexact result trap)

(CM) Enables/disables CM arithmetic traps.

Operation Notes

• If a trap is both enabled and armed, the user-written trap handler is invoked.

• If a trap is enabled but not armed, one of two situations apply:

  • If a Pascal/XL TRY statement was executed, pass control to the RECOVER block by doing an ESCAPE.

  • If a Pascal/XL TRY statement was not executed, an error message is output and the process aborts.

• If a trap is disabled, even though it is armed, the trap is ignored, and execution of the process continues without any interruption.

NOTE: By default, all traps (except the IEEE inexact result trap) are enabled and the system trap handler is armed.
