Spotting Qtplasmac

Here is the Gcode structure for spotting, it would be helpful if you help me see the gFormar.format structure, which is an array that contains the commands.
if (centerPunch) {
            writeComment("CENTER PUNCH THE HOLE ONLY");
            //writeBlock(feedOutput.format(99999));
            writeBlock(mFormat.format(3), $Format.format(2), sFormat.format(1)); //start the torch
            writeBlock(gFormat.format(91));
            writeBlock(gFormat.format(1), xOutput.format(0.00001));
            writeBlock(gFormat.format(90));
            //writeBlock("F#<_hal[plasmac.cut-feed-rate]>");
            //writeBlock(gFormat.format(0));
          }else {
 

Please try it if you can all the possible operations now I'm out of time, I tried some and it seems to work
