Special considerations for target file specification
In principle, there are two different ways of specifying a target file:
● NC notation:
The file is created in the MPF directory on the NC.
● DOS notation:
The file is written to the specified directory on the hard disk or on the specified PC,
provided that the directory is available on the hard disk or on a remote PC.
Note
Invalid variables generate a blank string in generated NC code and an error message in
the log book when they are read.
Special features of recompilation
The GC function cannot be called in sub-dialogs because variables originating from master
dialogs can be used in sub-dialogs. These variables would not, however, be available in
response to a direct call.
When generated code is processed manually with the Editor, the number of characters for
values created by the code generation program must not be changed. Changing these
values would make it impossible to recompile the code.
Remedy:
1. Recompile
2. Make change using the configured dialog. (e. g., 99 → 101)
3. GC
