Before you declare a variable, you must determine what kind of data you wish to store in that variable. As with most programming languages, a basic CPL variable can contain either some kind of number, or else some kind of text. The following table describes the types of variables supported by CPL.
Type |
Description |
int |
An integer value. The range of values it can store is from -2,147,483,648 to 2,147,483,647. |
float |
a floating point integer. Unlike an int, a float can store numbers with decimals. It can store a range of values from -2.2E-308 to 1.7E+308. |
char |
An ASCII character value from the range of -128 to 127. |
short |
A number value from -32,768 to 32,767. |
text |
Any text string including database field contents. |
Once you have determined what kind of variable you want, you can create the variable by declaring it. For more information, see Declaring a Variable. For more information on variable types, see Data Types in the CPL Language Reference.
