325B BatchModeEcho¶

Stub MON 325B (213 decimal) · Mnemonic MBECH · Group: Input and Output Monitor Calls (manual section 2.5)

Available from: Background programs (manual compatibility box)

Emulation source: src/handlers/mon_325B_BatchModeEcho.c

Description¶

Controls echo of input and output if the program is executed in a batch or mode job. The purpose is to allow the program to communicate with the terminal in mode jobs.

Notes¶

The state set by this monitor call is reset when the next batch or mode job starts.
This monitor call is mainly used by the JEC system.

Parameters¶

Name	Type	Direction	Description
`ControlBitmask`	INTEGER	I/O	Bit mask to set the echo. Bit 0 set to 1 means no echo in batch and mode executions. Bit 1 set to 1 means output on terminal from mode executions. Bit 2 set to 1 means input from terminal in mode executions. If the parameter is -1, the bit mask from the previous batch or mode job is returned in the A register (ASSEMBLY-500) or via the parameter (high-level languages).

Direction: In = the program supplies the value, Out = the call returns it, In/Out = both.
