response indicator when any valid command key other than the Enter key is

pressed by the workstation user.</p>

<div class="section"><p>One use of this function is to perform a simple test to determine

<p>See the <a href="s36env.htm">System/36 environment considerations for display files</a> topic for information

use of the indicator. This text's only function in the file or the program
|

is a comment. The single quotation marks are required. If you specify more

than 50 characters between the single quotation marks, the text is truncated

to 50 characters on the program computer printout.</p>
