The LOWER() function converts mark characters in a string to the next lower level mark.

 

 

Format

 

LOWER(string)

 

where

 

stringevaluates to the string in which mark characters are to be converted.

 

 

The LOWER() function replaces mark characters according to the following table:

 

OriginalReplacement
Item markField mark
Field markValue mark
Value markSubvalue mark
Subvalue markText mark
Text markText mark (unchanged)

 

 

Migration Note

 

Note that the behaviour in some other multivalue products may not be identical with regard to the effect of lowering a text mark.

 

 

 

Example

 

READLIST LIST THEN REC<4> = LOWER(LIST)

 

This statement reads active select list zero to LIST and then saves it in field 4 of REC. Because a select list contains field marks, the LOWER() function is used to demote each mark character to the next lowest mark.
