Old Pascal

These are some old Pascal-programs I wrote in Vax Pascal or Turbo Pascal between 1987 and 1992. You can run some of them in an DOS-emulator that is a Java applet: JPC.

I converted them from CP437 to UTF8 using iconv. There is one program, pu7.pas, that used ISO646-SE, but that was converted manually since it also uses square brackets for arrays.

I removed ^Z (end of file character) and changed CRLF to LF using sed -i -e 's/^Z//' -e 's/^M$//' filename.pas, where ^Z is entered by typing Ctrl+V Ctrl+Z in Bash, and ^M, Ctrl+V Ctrl+M.

An alternative is to use dos2unix:
iconv -f CP437 -t UTF8 filename.pas | tr -d '\32' | dos2unix > filename.pas2

Now you can compile to bubsigma, crcrcrlf, field, polsk, polsk2, and spridn using fpc (Free Pascal Compiler version 2.6.4 for Raspbian on Raspberry Pi). pu7 uses different file procedures. The other programs uses unit Graph which I can't use yet in Raspbian Linux with X.
