Maintaining The Exception Table - NCR 7158 Owner's Manual

0 0 1 0 0 1 0 0 (check #, four characters)
and 0 1 0 0 1 0 1 0 (account #, 10 characters)
then stored in the other three words of the table entry using:
0x1B 0x73 0x24 0x4A 27
0x1B 0x73 0x00 0x00 28
0x1B 0x73 0x00 0x00 29
Example 2
t22137-632t001 6042202o927540 2754 is the check serial #
6042202 is the account #
To load the third table entry, which starts at word 30, the transit
number 2137-632 would be stored in the first two words of its table
entry using this string of commands:
0x1B 0x73 0x22 0x13 30
0x1B 0x73 0x76 0x32 31
After the right transit symbol are four characters to skip, a seven digit
account number, two characters to skip, and finally a four digit check
serial #. The final character to skip need not be encoded. These would
be bitwise encoded as:
1 0 0 0 0 1 0 0 (skip four characters)
0 1 0 0 0 1 1 1 (account #, seven characters)
1 0 0 0 0 0 1 0 (skip two characters)
0 0 1 0 0 1 0 0 (check #, four characters)
then stored in the other three words of the table entry using:
0x1B 0x73 0x84 0x47 32
0x1B 0x73 0x82 0x24 33
0x1B 0x73 0x00 0x00 34.
