Turbo Pascal patches

The  following are some useful patches for Turbo Pascal 3.00B and 
above.  All  addresses  and data are given  in  hexadecimal.  The 
addresses are given for DEBUG. If you are using any other program 
to apply the patches,  you probably must subtract 100 (hex)  from 
the addresses.

To apply the patches using debug copy TURBO.COM to another file,
enter:   DEBUG (filename) <cr>   (Don't forget .COM !)
         e (address) (data, single bytes seperated by blanks) <cr>
         w <cr>
         q <cr>

Patch 1:  Change color settings in TP.
--------  This changes the colors in the Editor as well as those set by
          NormVideo and LowVideo.
          The addresses are the same for every version of TP.
            Normal Text:    177
            Bold Text:      178
            Marked Block:   179
            Error Messages: 17A
          Enter the color number at this address. High nibble -> background,
          low nibble -> foreground.
          Example: 1E at address 177 changes normal text to yellow on blue.

Patch 2:  Load error message file (TURBO.MSG) automatically at startup.
--------  Version      Address  Data
          3.00B plain  2EB7     B0 16 A2 48 03 90 90 90
          3.00B 8087   2980     B0 16 A2 50 03 90 90 90
          3.00B BCD    2DD8     B0 16 A2 7C 03 90 90 90
          3.01A plain  2F7D     B0 16 A2 48 03 90 90 90 

          At the address given above enter the bytes given under Data.  

Patch 3:  Beep on error during compilation.
--------  This has the side effect, that TP also beeps if you interrupt an
          operation in the Editor with Ctrl-U.
          Version      Address  Data
          3.00B plain  3213
          3.00B 8087   2CDC
          3.00B BCD    3134
          3.01A plain  32D9

          At the address given above, enter the bytes:
                   45 53 43 20 07

Patch 4:  Beep on end of compilation.
--------  Version      Addresses
          3.00B plain  3758, 3771
          3.00B 8087   3221, 323A
          3.00B BCD    3679, 3692
          3.01A plain  381E, 3837

          At both addresses given above enter the byte:
                   07

Patch 5: Stop creation of .BAK file.
--------  Version      Address
          3.00B plain  34A0
          3.00B 8087   2F69
          3.00B BCD    33C1
          3.01A plain  3566

          At the address given above, enter the bytes:
               90 90 90 90 90 90 90 90 90 90 90     (11x 90)

All  patches  were worked out by myself and though they work  for 
me, I cannot guarantee anything.

P.S.  forgot to mention:  patches are for IBM versions ONLY,  not 
for plain MS DOS.
