AGI_TNEW - Store a transformation in the database

Description:

The transformation defined by the pseudo-code FORTRAN statements DTOW and WTOD is stored in the database. The picture identifier signifies which picture is to receive the transformation structure. If this identifier is negative then the current picture will be used. If a transformation already exists for this picture then an error will be returned. The number of world variables NCW has to be equal to 2 otherwise an error will be returned. The number of data variables NCD also has to equal 2 in the present implementation.

Invocation:

CALL AGI_TNEW ( NCD, NCW, DTOW, WTOD, PICID, STATUS )

Arguments:

NCD = INTEGER (Given)

Number of data variables

NCW = INTEGER (Given)

Number of world variables

DTOW = CHARACTER $*$ ( $*$ )(NCW) (Given)

Array of forward transformation functions

WTOD = CHARACTER $*$ ( $*$ )(NCD) (Given)

Array of inverse transformation functions

PICID = INTEGER (Given)

Picture identifier

STATUS = INTEGER (Given and Returned)

The global status
