Hello Tom,
If ever you consider a port to an another language, I suggest Ada. Ada is issued from Pascal with strong type checking and more. (www.ada2012.org) It is an ISO standard. I port all my Pascal programs to Ada since 2000 and I'm very happy with it. I used P2Ada: http://p2ada.sourceforge.net.
I have some exemples on my web site (in French). Feel free to ask questions if you are interested in.
Regards, Pascal. http://blady.pagesperso-orange.fr

Scott:
What was wrong with getting a p2c translation (just curious). You only have to do the translation once, then you code in C after that.
I'm used to programming in Pascal, not C. Also, it's safer because of the type checking. If I switched I could never go back.
I used p2c (I assume we are talking about the same one). Its a very picky tool that crashes when you look at it funny, but I was able to get satisfactory results.
You are right about looking at it funny! One kind of bug(?) is that it changes how it handles i/o for the input file in the middle of the code. I haven't determined why but fortunately it's a rare problem.

Pascal:
I got the translator and compiler working but could not translate and compile a simple pascal program of my own.
verysimple.p - my pascal program verysimple.adb - my pascal program translated to Ada
When I try to gnatmake:
% gnatmake verysimple.adb gcc -c verysimple.adb verysimple.adb:32:01: no candidate interpretations match the actuals: verysimple.adb:32:01: missing argument for parameter "Item" in call to "put" declared at a-tienio.ads:50, instance at line 24 verysimple.adb:32:01: missing argument for parameter "Item" in call to "put" declared at a-tienio.ads:34, instance at line 24 verysimple.adb:32:01: missing argument for parameter "Item" in call to "put" declared at a-tiflio.ads:79, instance at a-lfteio.ads:18 verysimple.adb:32:01: missing argument for parameter "Item" in call to "put" declared at a-tiflio.ads:61, instance at a-lfteio.ads:18 verysimple.adb:32:01: missing argument for parameter "Item" in call to "put" declared at a-tiflio.ads:79, instance at a-flteio.ads:20 verysimple.adb:32:01: missing argument for parameter "Item" in call to "put" declared at a-tiflio.ads:61, instance at a-flteio.ads:20 verysimple.adb:32:01: missing argument for parameter "Item" in call to "put" declared at a-tiinio.ads:76, instance at a-inteio.ads:18 verysimple.adb:32:01: missing argument for parameter "Item" in call to "put" declared at a-tiinio.ads:60, instance at a-inteio.ads:18 verysimple.adb:32:01: missing argument for parameter "Item" in call to "put" declared at a-textio.ads:241 verysimple.adb:32:01: missing argument for parameter "Item" in call to "put" declared at a-textio.ads:207 verysimple.adb:32:05: expected type "Standard.Boolean" verysimple.adb:32:05: found private type "Ada.Text_Io.File_Type" verysimple.adb:32:05: ==> in call to "Put" at a-tienio.ads:40, instance at line 24 verysimple.adb:32:05: ==> in call to "Put" at a-tiflio.ads:68, instance at a-lfteio.ads:18 verysimple.adb:32:05: ==> in call to "Put" at a-tiflio.ads:68, instance at a-flteio.ads:20 verysimple.adb:32:05: ==> in call to "Put" at a-tiinio.ads:66, instance at a-inteio.ads:18 verysimple.adb:32:05: ==> in call to "Put" at a-textio.ads:242 verysimple.adb:32:05: ==> in call to "Put" at a-textio.ads:208 gnatmake: "verysimple.adb" compilation error
Any idea what I'm dong wrong?
Thanks,
