On the authors system this results in the following output:▼
<pre>
Buffer Height: 300
Buffer Width: 80
Window Height: 25
Window Width: 80
This perfectly demonstrates that the buffer may not be the same size as the window.

The <code>LINESIZE</code> built-in function returns the (terminal) screen's width. It is supported by most (classic) REXX interpreters (and some others) such as: CMS REXX, TSO REXX, VSE REXX, the IBM REXX compiler, PC/REXX, Personal REXX, REXX/imc, R4 and ROO. A sample usage of it is:
<lang rexx>width=linesize()</lang>
===
<code>SCRSIZE</code> is another built-in function, and returns two integers: the screen depth and the screen width. A few classic REXX interpreters support it: PC/REXX, Personal REXX, R4 and ROO.
