Performing concatenation.

Concatenation of a pair of transformations is performed by the routine TRN_JOIN (concatenate transformations), as follows:

CALL TRN_JOIN( LOCTR1, LOCTR2, ELOC, NAME, LOCNEW, STATUS )

where:

• LOCTR1 and LOCTR2 are locators to two existing transformations;

• ELOC is a locator to an existing HDS structure;

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

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

• STATUS is an inherited error status variable.

As with the TRN_NEW routine (Section ), a temporary transformation may also be produced by leaving the ELOC argument (and optionally the NAME argument) blank when TRN_JOIN is invoked.
