Sets the code page of an empty LONGCHAR variable. When
set to a valid code page, the code page of the specified variable
is fixed and overrides any default behavior in assignment operations
(including the COPY-LOB, OVERLAY, and SUBSTRING statements).

            longchar
          
 
          - The name of a LONGCHAR variable. The variable must be set to
the Unknown value (?) or the empty string (""). If the string
length is greater than 0, the AVM returns an error. 
 
        
        
          - 
            codepage
          
 
          - A character expression that evaluates to the name of a code
page. The name you specify must be a valid code page name available
in DLC/convmap.cp. If codepage is
the Unknown value (?), the code page of the LONGCHAR variable
is not fixed.
