1 You should also know that the conjugate base of a Bronsted acid is the species formed when a proton is lost from that acid (e.g., hydroxide ion is the conjugate base of water; water is the conjugate base of the hydronium ion).
Mainframe_Dinosaur Profile Answers by Mainframe_Dinosaur. Mainframe programmers wouldn't normally write a Cobol program just to count the number of records in a file. We would count the number of records using DFSort or SyncSort, or use AMS(Idcams repro). Both SORT and REPRO would be executed in a JCL stream. Much faster than writing a Cobol program.
For the variable length file (RECFM=V) the LRECL is the maximum record length in the file. The actual length, number of bytes in the record, is stored at the beginning of each record. This information is called the Record Descriptor Word (RDW). The RDW is a 4 byte Integer Binary (IB) field.
