HP COBOL supports a maximum of 8 MULTIPLE FILE TAPE clauses within a source program.
• Nesting depth
OCCURS clauses

HP COBOL program is 126.
• Prime key offset
For indexed files, the maximum offset of a prime key from the beginning of a record is 2,034,
which is an Enscribe record manager limitation.

There is no explicit limit on the number of internal or external records in a main program, a
called program, or a run unit.

The maximum number of receivers in an INITIALIZE statement is 127.

The maximum number of receivers in a MOVE statement is 255.
• References to level-88 condition-names in a program
A condition-name can be defined in the Environment Division (associated with an external
