#### 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)

##### WTOD = CHARACTER
$\ast $ (
$\ast $ )(NCD)
(Given)

Array of inverse transformation functions

##### PICID = INTEGER (Given)

Picture identifier

#####
STATUS = INTEGER (Given and Returned)

The global status
