X 6.2.12 ENTRY Statement
X The ENTRY statement establishes an alternate entry point into a COBOL
X called subprogram.
X The ENTRY statement cannot be used in:
- X Programs that specify a return value using the Procedure Division
X RETURNING phrase. For details, see the discussion of the RETURNING
X phrase under "The Procedure Division Header" in topic 6.1.2. - X Nested program. See "Nested Programs" in topic 2.1.1 for a
X description of nested programs.
X When a CALL statement naming the alternate entry point is executed in a
X calling program, control is transferred to the next executable statement
X following the ENTRY statement.

X Must be nonnumeric and conform to the rules for the formation of a

X topic 3.1.1).
X Must not match the program-id or any other ENTRY literal in this
X program.
X Must not be a figurative constant.
X Execution of the called program begins at the first executable statement
X following the ENTRY statement whose literal corresponds to the CALL
