Specifies a truth value indicating whether GT.M treats labels as case sensitive or not.

This factor can be modified at run-time by using the VIEW command with an argument having "LABELS":"LOWER" or "LABELS":"UPPER" for a value. At compile-time, this factor can be controlled by the /LABELS= qualifier on the MUMPS command.

Note that it is important to have this switch in the same position for both compiling and running application images.
