I've been playing around with Excel to produce "scripts" without the .scr file. If you arrange your commands vertically down the columns, its a simple select, copy & paste into the command line. I'm using this method to avoid sifting through the .scr file and manually changing values for alternative configurations. See attached stair layout table clip. This sheet is still a work in progress. The Excel formulas can be a bit tricky & time consuming but is worth the effort.
