IBM 2790, Manual

TRLIST macro is followed by one or more DEULIST
macros. The first transaction list must be for all of the
IBM 1035 Badge Readers. This consists of a TRLIST
macro instruction followed by one DEULIST macro
instruction.
The transaction list tables created by the TRLIST,
ASLIST, and DEULIST macro instructions are composed of:
a header, and an internal message, and/or from one to sixteen
data entry steps. The header information is provided in the
TRLIST macro instruction. The TRLIST macro must follow
the last TGROUP macro.
ASLIST. The ASLIST (area station list) macro instruction
is used to define one step of a transaction list for a 2791
Area Station. One to sixteen ASLIST macros may follow
a TRLIST macro; the last ASLIST macro may define an
internal message.
DEULIST. The DEULIST (data entry unit list) macro is
used to define one step of a transaction list for a data
entry unit. For a 2796 DEU one to thirteen DEULIST
macros and for a 2795 DEU one to sixteen DEULIST mac­
ros may follow a TRLIST macro; the last DEULIST macro
may define an internal message.
STEND: The STEND macro is used to indicate the end of
all user macros and must be the last card processed before
the assembler END card.
The STEND macro compares the total number of bytes
generated for the 2715 user tables with the maximum
allowable size for the user’s particular 2715 configuration.
If the table size exceeds the allowable maximum, MNOTE
is issued indicating that the assembly is invalid.
After the macros have been translated to object format,
the user’s problem program can transmit them to the 2715
by reading the object module (without using LINK-EDIT),
formatting each card into a 2715 message, and using normal
BTAM BSC WRITE facilities.
User Table
Figure 31 shows a simplified version of a user table that
is designed to show the relationship of the various macro­
generated tables.
Area Station Data Entry. The area station address (AS ID)
is used to find the correct transaction group (TG) from
the area station table (AS table).
The transaction code (TC) is used to find the correct
transaction list from the transaction group table (TG table).
The transaction list plus the step number from the area
station sequence table is used to find the correct step from
the transaction list table (TR List table). The transaction
list step contains the information necessary for the micro­
code to process the data entry.
DEU Data Entry. The area station address (AS ID) is used
to find the correct transaction group (TG) from the DEU
table.
The transaction code (TC) is used to find the correct
transaction list from the transaction group table.
The area station address is used to find an address from
the DEU index table. The index table address plus the DEU
address is used to find the correct step from the DEU se­
quence table.
The transaction list plus the step number from the se­
quence table is used to find the correct step from the trans­
action list table (TR List table). The transaction list step
contains the information necessary to process the data
entry.

plan a 2790 system program. The forms are designed to be
used as master copies for copying on office copy equipment.
In addition to these forms, the
IBM 2790 Data Communi­

Area Station and Data Entry Unit Table (Figure 32)
Area Station Identification
Location. This is an information column to be used to
locate the station in relation to your own shop. Enter the
department, building, floor, etc.
#00-99. Enter the numerical area station ID, permissible
numbers are 00-99. Numbers need not be consecutive,
but must be unique and ascending.
Transaction Group Name
Area Station. Each area station is associated with a trans­
action group table; all area stations to have the same pro­
grammed capability are associated with the same table.
Enter the name (up to eight characters) of the transaction
group table to which this area station is to be associated.
Data Entry Units. Each data entry unit is associated with
a transaction group table; all data entry units attached to a
given area station are associated with the same table. All
data entry units to have the same programmed capability
are associated with the same table. Enter the name (up to
eight characters) of the transaction group table to which
the data entry units attached to this area station are to be
associated.
Up to 63 transaction group tables are possible.
