TTGEN - ZCOM System Table Generator
Creating the TTGEN Configuration File
Chapter 2 59
Pterm
A method of defining a physical terminal which has a number of logical
terminals associated with it. The subparameter Term, above, creates a
one-to-one correspondence of physical terminals to logical terminals.
Thus Pterm consists of a subset of the subparameters used for the Term
parameter. (See under Term above.)

Lterm
Each logical terminal that is to be linked to the physical terminal, as
described in Pterm above, must be defined in this section under this
parameter. The logical terminal subparameters are a subset of those that
occur in the Term parameter of the Terminal-Definition section of the
TTGEN configuration file. (See under TERM above.)
Lterm ZLU type logical_address appl inst brnch work area “desc”
logical-address A hexadecimal field up to 20 hex digits (i.e., 10 bytes).
It is intended to be used by application programs to
associate unique IDs to LTERM terminals that belong
to the same PTERM terminal. The ZCOM routine
ltfind is provided to search a group of logical terminals
for a specific logical address field.
Ldata
This subparameter allows the user to set up and initialize a buffer of
values in a Logical-Data area of the logical terminal table (LTT)
extension area.
The Ldata subparameter is related to the previous Lterm or Term
parameter that came before it. In other words, the affected LTT
extension area belongs to the LTT created for the previous Lterm or Term
parameter. An Ldata subparameter after a Pterm parameter will cause
an error to be reported.
Note that a Logical-Data area must be defined before you can use the
Ldata parameter. Ldata can be offset anywhere within its Logical-Data
area. Multiple Ldata areas in the same Logical-Data area must not
overlap or go beyond the end of the Logical-Data area.
