Get Parameter From Command Line And Parsing Values In PowerBuilder

Get parameter from command line and parsing values

String ls_cmd, ls_arg[]
Integer i, li_argcnt

// Get arguments and strip blanks from start and end of string
ls_cmd  = Trim( CommandParm () )

li_argcnt = 1
Do While Len(ls_cmd ) > 0
	// Find first blank
	i = Pos( ls_cmd, " " )
	// If no blanks (only one argument), set i to point to the hypothetical character after end of string
	If i = 0 Then i = Len(ls_cmd) + 1
	// Assign the arg to the arg array.No. of chars copied is one less than position of the space found with Pos
	ls_arg[li_argcnt] = Left( ls_cmd, i - 1 )
	// Increment the argument count for the next loop
	li_argcnt = li_argcnt + 1
	// Remove the argument from the string so the next argument becomes first
	ls_cmd = Replace( ls_cmd, 1, i, "" )
Loop

Loop

Good Luck!
