Using GLOBAL as the Name of a Variable
If you attempt to define a variable with the name global,
the define operation fails. The syntax that the following example
shows conflicts with the syntax for defining global variables:
DEFINE global INT; -- fails;
If the DELIMIDENT environment variable is set, you could
use global as a variable name, as the following example shows:
DEFINE "global" INT; -- successful
Important: Although workarounds that the preceding
sections show can avoid compilation or runtime syntax conflicts from
keywords used as identifiers, keep in mind that such identifiers tend
to make code more difficult to understand and to maintain.
