Variables (Corel Paradox and Java Cross Reference Guide)

Declaring variables is optional unless you click Program | Compiler Warnings while in the ObjectPAL editor for every form, script, and library you create. Using Compiler Warnings is strongly recommended to avoid incorrectly typing an existing variable and to avoid any confusion about variable scope. Also recommended is turning on Compile with Debug for every form, script, and library too for tighter, cleaner code.

Undeclared variables are AnyType variables. Common data types include Currency, Date, Datetime, Logical, LongInt, Number, SmallInt, String, and Time.

var
    FullName String
    Age SmallInt
    Weight Number

endVar

FullName = "Mike Prestwood"
Age = 32
Weight =154.4

msgInfo("", FullName + ", age=" + String(Age) 

             + ", weight=" + String(Weight))

 ObjectPAL Variables (var x SmallInt endVar)  

Variable names are case sensitive.

The Java basic types are boolean, byte, short, int, long, float, double, and char. You can also declare a variable to hold a particular instance of a class such as String.

int a;

int a, b;

int age = 43;

String FullName;
