This subroutine returns the name of the input image as a character string.

CALL IMG_NAME( PARAM, VALUE, STATUS )

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

VALUE = CHARACTER $\ast$ ( $\ast$ ) (Returned)

STATUS = INTEGER (Given and Returned)

• The character string VALUE should be made large enough to contain the full name of the image.

• This subroutine will directly access an image if an association has not already been made. Note that it will be opened for read-only access and you will not be able to write or delete any header items. If you need to be able to do this then access the image first, either with one of the ??x]]IMG_MOD[n][x] subroutines (if you intend to process the image data), or the HDR_MOD subroutine.
