User data are variables that are used internally by both ShopTurn and
G-code programs. These user data can be displayed in a list.
The following types of variables are defined:

Global User Data (GUD)
Global user data is valid in all programs.
The display of global user data (GUD) can be disabled via
keyswitch or password.

Local User Data (LUD)
Local User Data is only valid in the program or subroutine in which
it was defined.
During program execution, ShopTurn displays the LUDs that are
present between the current block and the end of the program. If
you press the "Cycle Stop" key, the LUD list is updated. The
values, however, are continuously updated.

Global Program User Data (PUD)
Global program user data is created from the local variables (LUD)
defined in the main program.
PUD is valid in all subroutines, where it can also be read and
written.
The local data is also displayed with the global program user data.

Channel-specific user data
Channel-specific user data is only applicable in one channel.
