{ In TP there is, of course, ParamCount and ParamStr. The actual command line can be found in the PSP segment, at offset $80 (hexadecimal). The Byte at $80 contains the count of Characters, including the leading delimiter Character (usually a space). In TP the PSP segment may be accessed using PrefixSeg. Note that TP omits the carriage-return that normally appends the input Character line. This is a problem For Programs that look For it as the end of the String. If you're using a non-TP compiler, you'll need to get the PSP segment value via a Dos Function $62 call. Here's a simple TP Program to illustrate. Compile it, then invoke it With some command-line input... } (*********************************************************************) Program CommandLine; { CL.PAS } Var CharCount, i : Word; begin CharCount := Mem[PrefixSeg:$80]; { number of input Characters } WriteLn('Input Characters: ', CharCount ); For i := 1 to CharCount DO Write( CHR( Mem[PrefixSeg:$80+i] )); WriteLn; end.
