Basics of ZPL

Declaring Variables

•Variable declarations have the form of a list followed by colon (:) followed by a datatype

var x, y, z : double;

•The type of an array is a pair

[<region>] <data type>

•The region can be named or explicit

var A, B, C : [R] double;

Small_data : [1..n] byte;

•Arrays passed as parameters must have this type given in the formal parameter
