The following fixes I were routed from germany:

=========================

crt.pas Line 199 (sometimes wierd colors):
  vioscrollup(0,0,24,79,1,cell,0);
                        ~ instead of 25

**********************    F I X   # 2 ************************************

fctl.asm Line 139 (Rewrite didn't overwrite an existing file):
    MOV     AX,FILE_CREATE OR FILE_TRUNCATE; Read flags for new file
instead of                    ~~~~~~~~~~~~~
    MOV     AX,FILE_CREATE OR FILE_OPEN;  read flags for new file

**********************    F I X   # 3   **********************************
Problem Report:
;  Command line parameter with mutliple spaces between them were ignored.
;
;  Program test.pas;
;  begin writeln(paramcount) end.

;  c>TEST 1 2  3 4 5

;    returns 2 instead of 5.

Solution:
   Replace   WPAR.ASM with the one in this Archive.

NOTE:  the WPAR.ASM in this Archive ADD 2 additional Features to
       ParamStr:

       ParamStr(-1) : returns Complete CMDLINE as typed in by User.
                      With a #0 between Program Name and Parameter list.
       ParamStr(-2) : Returns Only the Parameter List as typed in by User.

           Also,  If the CMDLINE or Parameter List is > 255 char long, then
           the result is truncated to 255 chars.
