Dialog texts in subprogram call
You can define up to 30 parameter descriptions that precede/follow
the input fields in an external subprogram. The units of measure are
defined using code numbers. Depending on the setting "metric" or
"inches," the control shows the designations (of the units of measure).
When calling external subprograms that contain a parameter list, then
parameters not contained in this list are omitted from the call dialog.
The parameter descriptions can be positioned within the subprogram
as desired. The control searches for subprograms in the sequence:
current project, standard directory and then machine manufacturer
directory.
Parameter descriptions (see table at right):
[//] – Beginning
[pn=n; s=parameter text (up to 25 characters) ]
[//] – End
pn: Parameter designations (la, lb, ...)
n: Code number for units of measure
 0: Non-dimensional
 1: mm or inches
 2: mm/rev or in./rev
 3: mm/min or in./min
 4: m/min or ft/min
 5: Rev/min
 6: Degrees (°)
 7: µm or µinch
