Creating a Transformation

The transformation functions formulated above may be used to create an HDS transformation structure by calling the routine TRN_NEW (create new transformation), as follows:

CALL TRN_NEW( NVIN, NVOUT, FOR, INV, PREC, COMM, ELOC, NAME, LOCTR, STATUS )

where:

• NVIN and NVOUT are the numbers of input and output variables;

• FOR and INV are the two character arrays containing the forward and inverse transformation functions;

• PREC is a character expression specifying the arithmetic precision with which the transformation functions will be evaluated;

• COMM is a comment to be stored with the transformation;

• ELOC is a locator to an existing HDS structure;

• NAME is the HDS name of the new structure component to be created;

• LOCTR returns a locator to the newly created transformation structure;

• STATUS is an inherited error status variable.
