History of executed query commands in isql

I am using IBM-Informix ISQL version 7.50.UC3.
I wanted to know what is the command that can be used to retrieve the
history of executed SQL's in isql.
Ex: say 5 users executed select queries and 3 delete queries. so, I want
to know the exact queries these users have used in isql enviroment
