ARY_BASE  -  Obtain an identifier for a base array

Description:
The routine returns an identifier for the base array with which an array section is associated.

Invocation:
CALL ARY_BASE( IARY1, IARY2, STATUS )

Arguments:
IARY1 = INTEGER (Given)
Identifier for an existing array section (the routine will also work if this is already a base array).
IARY2 = INTEGER (Returned)
Identifier for the base array with which the section is associated.
STATUS = INTEGER (Given and Returned)
The global status.

Notes:
  • If this routine is called with STATUS set, then a value of ARY__NOID will be returned for the IARY2 argument, although no further processing will occur. The same value will also be returned if the routine should fail for any reason. The ARY__NOID constant is defined in the include file ARY_PAR.
