you can get it – I don’t know how VAX software is distributed) and converts it to C code. You’d have to write wrappers that emulate VAX library routines using posix routines.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Tgat looks like vt52 sewuence. To work on more terminal screens you might want to upgrade to ansii vt100 at leasr. Some terminals dont understand the vt52 codes.<br>

<p class="MsoNormal">Another issue I'm running into which should be fun, is VT escape sequences<br>
<br>
eg:<br>
170 PRINT ESC+"Y"+CHR$(53)+CHR$(33);\INPUT #1;"PRESS RETURN TO CONTINUE";A$<br>
<br>
That puts the cursor at a specific place on screen,<br>
these were built on VT-52 and VT-100 terminals with fixed screen size.<br>
using Linux you can get ANSI support, but the screen could be a vastly different size,<br>
of course, we can just make it run like normal.<br>
<br>
the other problem is the escape sequences themselves may not work any more.<br>
they seem to work in Linux with ANSI enabled,<br>
will they work on Mac CLI (maybe) or DOS/Windows ? portability is important.<br>
<br>
But, I'm not going to do a ton of work writing cursor routines for a dozen basic programs from the 80's.<br>
<br>
and btw freepascal has incredible string handling for those doubters out there...<br>
