It's pretty straightforward to do this. In order to accept command line parameters, you need to have a PARAMETERS (or LPARAMETERS) statement as the first executable line of your main program. For example, if you wanted to accept up to 3 command line arguments, and make them available to a parser in an argument array:

PARAMETERS uArg1, uArg2, uArg3  && as many as you think you might need
*  Save the parameters in an array for later use in this case
LOCAL nParmCount, i
DECLARE aParms[1]
aParms = NULL
nParmCount = PCOUNT()
FOR i = 1 TO nParmCount
   DECLARE aParms[i]
   aParms[i] = EVAL('uArg'+ALLTRIM(STR(i))
ENDFOR
IF nParmCount > 0
   *  Pass the array of parameters to your command line parser or whatever
ENDIF
