NEX Recalls the next record. If no value is entered for the Ordinate, the first record in
Ordinate order is retrieved.

INQ Brings a record into memory (you must code logic to recall it to the screen).
Note: The English values ADD, CHG, DEL, PUR and INQ are contained in the items
GLB.ADD, GLB.CHG, GLB.DEL, GLB.PUR and GLB.INQ, respectively. These
items may be translated. See the LLANGUAGE file details in the
multiple-language section of your LINC Administration and Operations Guide
for the relevant host type.
Five values of MAINT (FIR, LAS, NEX, BAC, REC) provide recall functions, and have the
following restrictions:
$ They are only available if the AUTO.RECALL option has been set on the Component
Options screen.
$ They are not available if the Component has a Usage Output Ordinate.
$ They do not change any values stored in the LINC database (including the value of
MAINT).
All of the values in the table are described in more detail in the following subsections.
LENGTH = 3 (1 in the LINC database) EDIT = A
ADD Value for MAINT
A MAINT value of ADD (or its translated equivalent in GLB.ADD) is used to add new
records.
On the Ispec screen, this is the default value for the MAINT field.
In the database, the record will have the value A.
