The declaration section contains declarations or definitions of
constants, labels, user-defined data types, variables, and
user-defined functions and procedures. In addition, only
modules can contain initialization and finalization sections.
Each appears in a subsection introduced by a VSI Pascal reserved
word.
These sections appear after the header and before the executable
section (if any). The TO BEGIN DO and TO END DO sections can
appear only in modules and can appear only once within a module.
The remaining sections can appear in programs, modules,
functions, or procedures; they can appear more than once and in
any order in a single declaration section. If you use one kind
of section more than once in a declaration section, be sure to
declare types, variables, and constants before you use them in
subsequent sections.
If you want to apply the HIDDEN attribute to all of the data in
a declaration section, place the HIDDEN attribute immediately
preceding the section header, as follows:
[HIDDEN] CONST
