As the PCI works through your instruction list, all the usual cycle prompts will be presented to the user. Where specified, full input dialogs will also be presented. The sequence of instructions generated will be added to the Sequence Window as they are completed.
If you wish to give the PCI user additional information then comment instructions can be placed in the sequence of instructions by using the Comment (M-Functions menu) command . Comments will be added to the NC file if the sequence is passed to the Code Generator.
Example

Comments beginning with a ‘?’ will be converted to user prompts (using
the PCI %DISPLAY directive) and will not appear in the sequence or NC
file created when the PCI is used.
Alternatively, additional PCI prompts and instructions can be added afterwards using an editor. See Finishing the PCI.
