Normally, the handles to HDS data files are locators and files are obtained via the parameter system. However, some applications can generate sensible names, especially when dealing a long series of files that are to be created without manual intervention. There is no direct mechanism in the user-level parameter-system library to put a name into the associated parameter. This routine provides that functionality.

CALL AIF_PTFNM( PARNAM, FILNAM, STATUS )

PARNAM = CHARACTER $\ast$ ( $\ast$ ) (Given)

FILNAM = CHARACTER $\ast$ ( $\ast$ ) (Given)

STATUS = INTEGER (Given and Returned)

• This cannot be used to obtain the names of objects within an HDS file.

• Must have obtained the file via the input parameter.
