7.64 KEEP_MAX

The KEEP_MAX command is used to keep the value of the field having the maximum value of field(s) in another field.

Note: Full RDMLX Fields cannot be used with this command.

The KEEP_MAX command is only valid within SELECT or SELECTLIST command loops, because the processing logic used is implicitly linked to the SELECT / SELECTLIST loop logic.

Normally the KEEP_MAX command is entered directly after the SELECT or SELECTLIST command. However there are specific exceptions to this. Refer to the examples section for more details.
