User`s manual

Scope, or identifier visibility, determines if identifier can be referenced in certain

part of the program code. Location of identifier declaration in the code determines

its scope. Identifiers with narrower scope - especially identifiers declared in func-

tions and procedures - are sometimes called local, while identifiers with wider

scope are called global.

All functions and procedures are visible in the whole project, and they are visible

in any part of the program or any module. Constants not local for a procedure or

function are also visible in the whole project. Local constants are visible only in

procedure or function body in which they are declared.

Rules for determining the variable identifier scope are summarized below:

- If the identifier is declared in the declaration of a main module, it is

visible from the point where it is declared to the end of the module.

- If the identifier is declared in the declaration of function, or procedure, its

scope extends from the point where it is declared to the end of the current

block, including all blocks enclosed within that scope.

- If the identifier is declared in the implementation section of a module, but

not within the block of any function or procedure, its scope extends from

the point where it is declared to the end of the module. The identifier is

available to any function or procedure in the module.

PIC SFR (Special Function Registers), are implicitly declared as global variables

of byte type. Their scope is the entire project and they are visible in any part of the

program or any module.
