"Machine" operating area.
Program selection
Select the workpieces (WPD), main programs (MPF) or subprograms (SPF) by placing the
cursor on the desired program or workpiece.
For workpieces, the workpiece directory must contain a program with the same name. This
program is automatically selected for execution (e.g. when you select the workpiece
SHAFT.WPD, the main program SHAFT.MPF is automatically selected).
If an INI file of the same name exists (e.g. SHAFT.INI), it will be executed once at the first
part program start after selection of the part program. Any additional INI files are executed in
accordance with machine data MD11280 $MN_WPD_INI_MODE.
