Code Data Type

Denotes a special type of string that is converted to uppercase and removes any trailing or leading spaces.

Remarks

The length of a Code variable equals the number of characters in the text without leading or trailing spaces.

You must specify the length of a Code variable or field. The maximum length of a Code variable is 1024 characters. The maximum length of a Code field in a table is 2048 characters. A Code variable cannot be null. The Code data type supports Unicode.

You can index any character position in a string, such as A[65]. The resulting value will be a Char Data Type. You cannot assign a char to a position in the code variable greater than the current length of the variable +1.

Fields that contain a date formula must not have data type Code. Instead, use the DateFormula Data Type. All fields that contain a date formula with data type Code must be converted into data type DateFormula.

Example

This example shows some typical examples of code string assignments. In these examples, assume that the variable c is a code variable with a maximum length of 4.

c := 'ABC';   
// Results in variable c, which contains 'ABC'   
// and is 3 characters in length.  
c := '1';  
// Results in variable c, which contains '1'   
// and is 1 character in length.  
c := '';  
// Results in variable c, which contains '' (empty string)  
// and is zero (0) characters in length.  
c := ' 2 ';  
// Results in variable c, which contains '2'  
// and is 1 character in length.
