A GLOBALS PDF is a PDF that defines global variables. The structure is:
GLOBALS HELP=help-location definitions of global variables declarations of referenced globals declarations of local variables END-PROC
Global variables are defined using PARM commands in global PDFs. See Section 3.3.2 for details on global variables.
A GLOBALS PDF may contain references to other globals and declarations of local variables. Such references are useful for setting up a constant to initialize subsequent globals in the same PDF.
The declarations and definitions in a GLOBALS PDF may be grouped under subcommands.
