SUBROUTINE HSI1_ADD( NARG, ARGS, OARG, STATUS )
*+
* Name:
* HSI1_ADD
* Purpose:
* Create a new history record in an HDS file
* Language:
* Starlink Fortran
* Invocation:
* CALL HSI1_ADD( NARG, ARGS, OARG, STATUS )
* Description:
* Creates a new history record in an HDS file.
* Arguments:
* NARG = INTEGER (given)
* Number of method arguments
* ARGS(*) = INTEGER (given)
* ADI identifier of method arguments
* OARG = INTEGER (returned)
* Output data
* STATUS = INTEGER (given and returned)
* The global status.
* Examples:
* {routine_example_text}
* {routine_example_description}
* Pitfalls:
* {pitfall_description}...
* Notes:
* {routine_notes}...
* Prior Requirements:
* {routine_prior_requirements}...
* Algorithm:
* {algorithm_description}...
* Accuracy:
* {routine_accuracy}
* Timing:
* {routine_timing}
* External Routines Used:
* DAT:
* CMP_PUT0x - Write value of HDS component
* DAT_ANNUL - Release an HDS locator
* DAT_ERASE - Erase an an HDS component
* DAT_FIND - Find an HDS component
* DAT_NEW[0x] - Create new HDS component
* DAT_THERE - Does an HDS component exist?
* Implementation Deficiencies:
* The constants in this routine should be loadable resources. This
* would enable the user to turn off all history creation (somehow).
