HT


>>-HT----------------------------------------------------------><

HT (Halt Typing) is an immediate command you can use to suppress terminal output that an exec generates. The HT immediate command is available only if an exec is running in TSO/E and you press the attention interrupt key to enter attention mode. You can enter HT in response to the REXX attention prompting message, IRX0920I.

After you enter HT, the exec that is running continues processing, but the only output that is displayed at the terminal is output from TSO/E commands that the exec issues. All other output from the exec is suppressed.

Example

You are running an exec in TSO/E that calls an internal subroutine to display a line of output from a loop that repeats many times. Before the exec calls the subroutine, the exec displays a message that lets you press the attention interrupt key and then suppress the output by entering HT. When the loop is completed, the subroutine issues EXECUTIL RT to redisplay output.
