7.84 KEEP_MIN
The KEEP_MIN command is used to keep the value of the field having the minimum value of field(s) in another field.
The KEEP_MIN 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_MIN 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.
