7.82 KEEP_COUNT
The KEEP_COUNT command is used to keep count of field(s) changes in another field.
The KEEP_COUNT 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_COUNT 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.
