In Turbo Pascal (at least 3.0), there are two variables called ParamCount and
ParamStr.  ParamCount is of type integer and contains the number of blank-
separated parameters on the command line.  

ParamStr is an ARRAY of strings, each string being the appropriate parameter,
starting at index 1 (It may be 0)

If I remember correctly, standard Pascal has no method on reading in the com-
mand line parameters.  It is completely implementation specific.
