Robert Wallick: created )SI State Indicator documentation page
2015-07-15T18:05:12Z
<p>created )SI State Indicator documentation page</p>
<p><b>New page</b></p><div><big>)SI - Show the '''State Indicator''' or workspace Status Indicator:</big><br />
<br />
Example:<br />
<pre><br />
)SI<br />
Function2[7] *<br />
Function1[5]<br />
</pre><br />
<br />
In the above function, Function1 called Function2 at line 5 within Function1. &nbsp;Then Function2 became suspended (note the *) at line 7 in Function2. Function1 does not have an asterisk next to it, so it is called a pendent or pending function - pending resolution or correction of Function2[7] line 7 - wherein APL's Interpreter was suspended or stopped. Note that '''the most recent interruption''' is listed at the '''<u>top</u> of the State Indicator stack.''' The topmost function is where an error occurred or processing was suspended/halted/a break occurred - and is where you or an APL system programmer needs to most closely scrutinize or debug the APL coding.<br />
<br />
<br>)SI lists user functions and operators (and their associated line numbers) in the current APL workspace '''state indicator''' with an asterisk(*) for all immediate execution expressions that were suspended.<br />
<br />
<br>)SI is useful for debugging purposes and as a reminder of where you the APL programmer or an APL user encountered an error. )SI is saved when the workspace is )SAVE'd and is available for the next APL/NARS user session.<br />
