Understanding global blocks
Global symbols can be defined with the GLOBALS instruction
The GLOBALS
instruction can be used to declare variables, constants and types
for the whole program.
Important: Defining global elements shared by all modules of a program is an
old programming concept. To increase code re-usability and readability, avoid global
elements in your programs. Use modular concepts instead, by defining
PUBLIC
variables, constants and types in modules that will be
imported into other modules with the IMPORT FGL
instruction.
