Purpose

IN_ALPHA_NLS tests whether a value is contained within a specified alphanumeric or wide string. It searches a string character by character, not byte by byte. This permits easy search of international characters.
 

Syntax

IF value IN_ALPHA_NLS ‘string’ THEN statement;
 

Operation

value is an alphanumeric, wide, or combined value variable. Value may be either a value variable or a scratch variable.
string is an alphanumeric, wide, or mixed multi-byte valued variable. String may be either a value variable or a scratch variable..
 

Remarks

The use of IN_ALPHA_NLS enables applications to be compatible across mixed-byte language sets. This function differs from IN-ALPHA in that IN_ALPHA_NLS is character based, not byte based.
