#Option Explicit

Syntax:

    #option explicit

This option ensures that all variables are dimensioned in the user program. The scope is the user code only and no other code space like .h or include files.

#option explicit requires all variables,including bytes, in the user program to be defined.

Variables can be defined and not used within your user program. Unused variables will not allocate memory.

Introduction:

Example:

    'Set chip model
    #chip 16f877a

    'Example command
    #option explicit

    dim myuserflag as byte

    myuserflag = true
