Table Maintenance file format
The file format for a table used for maintenance is similar to that used by
table data validation in that it uses a header record to describe the table
format to the TriCoder. The header consists of at least 11 characters plus a
comment or reference name. The table maintenance header uses the
following format:
Position data allowed
x U 0r F
01-20
aa
xbb x00-x20
x00-x20
xcc
x00-x20
xdd
comment 1-15
alphanumeric
Lets say we wanted to create a file that had a 5 digit item number (the key
field), a Fixed 16 character description, an Updatable 6 digit price, an
Updatable 4 digit quantity count and a file reference of INVENTORY. The
header for such a file would look like this:
The entire file might look something like this:
description
data maintenance on table 1
data maintenance on table 2
data maintenance on table 3

U indicates field is UPDATABLE
F indicated field is FIXED

not present

field is not used by the TriCoder.
