3.19.2 GLOBAL Instruction
Up to 1000 local jump labels can be defined in each of the files linked with USES.
Modules defined in one file must be defined globally before they can be called from another file.
This is done with the GLOBAL instruction at the beginning of the file.
Jump labels can only be defined globally when they are defined as LBL later on in the program (and
not as KFIELD!).
Syntax:
GLOBAL jump label ;declaration of "jump label" beyond the file boundary
GLOBAL definitions must not be written in the main program. A single jump label cannot be
declared globally by more than one module, however a name that has been declared globally by file
A can be used again locally in file B.
In all, 1000 jump labels can be defined globally by all modules.
