The equate statement is a compiler directive that declares a constant at compile time or a synonym of another variable or array element.
Syntax
equate symbol to char(constant) {,var to exp...} equate symbol to var |
Synonym(s)
equ |
Description
NOTE |
Expressions in an equate statement are limited to constant expressions, variables, and character strings. |
The equate statement can also be used to assign meaningful variable names to array elements. Once equate has been used to assign a value to a symbol, the variable cannot be used as a variable and cannot be reassigned a value. equate definitions must be placed before any usage of the equated symbols. Failure to do so can generate compile-time errors.
Example(s)
equ form.feed to char(12) equ ring.bell to char(7) equ attribute.mark to char(254) ... read array from file,ID... amcmax = dcount(array,attribute.mark) ... if ctr=pagemax then print form.feed crt ring.bell: end ... |
