PowerBuilder: 以下内容为程序代码:
string ls_cmd, ls_arg[]
integer i, li_argcnt
// Get the arguments and strip blanks // from start and end of string ls_cmd = Trim(CommandParm())
li_argcnt = 1 DO WHILE Len(ls_cmd) > 0
// Find the first blank i = Pos( ls_cmd, " ")
// If no blanks (only one argument), // set i to point to the hypothetical character // after the end of the string if i = 0 then i = Len(ls_cmd) + 1
// Assign the arg to the argument array. // Number of chars copied is one less than the // 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, "")
