IBASIC Controller

PROGram Subsystem

Example 8-43 Syntax

PROGram[:SELected]:WAIT

Example 8-44 Example

OUTPUT 714;"PROGram:SELected:WAIT"

OUTPUT 714;"PROG:WAIT"

:WAIT? The :WAIT? query command stops the Test Set from executing

any commands or queries received through HP-IB until after the

IBASIC program exits the RUN state, that is - the program is either

PAUSED or STOPPED. A 1 is returned in response to the :WAIT? query

command when the IBASIC program is either stopped or paused.

CAUTION

When the :WAIT? query command is sent to the Test Set the program

running on the external controller will hang on the enter or input

statement until the IBASIC program is either STOPPED or PAUSED.

This is due to the fact that the HP-IB bus and the external controller

will be in a temporary holdoff state while waiting for the Test Set to put

a 1 into the Output queue to satisfy the :WAIT? query command.

Example 8-45 Syntax

PROGram[:SELected]:WAIT?

Example 8-46 Example

OUTPUT 714;"PROGram:SELected:WAIT?"

ENTER 714;Dummy

OUTPUT 714;"PROG:WAIT?"

ENTER 714;Dummy

Consider the following example where the user wishes to determine,

from an external controller, if the IBASIC program running on the Test

Set has finished executing. The example programs show how this might

be accomplished with and without using the :WAIT? query command.
