PROGRAM CARD CODES
A program card, which is a basic part of program control, is
prepared for each punching application. Proper punching in
this program card controls automatic operations for corre-
sponding columns of data cards being punched or verified.
Each row in program card governs a specific function. (See
Figure 5.)

Notes for Figure 5:
1. Program codes apply in program levels 1-6. Program level 0
is 80 single-position fields, alpha shift.
2. If lZ control in units position verify is not desired, do not
use 3-punch in units position.
3. Only field definition is required for lZ punching. Program
cards coded for
lZ
in veri fy mode (3-punches) may be used in
punch mode without alteration because machine ignores 3-
codes in punch mode, unless direct punch control feature is
used (see chart).
4. Minimum field size is two columns for accumulate, self
check, and lZ.
5. Maximum field size is 79 columns for self check and lZ.
6. Maximum input field size for accumulate is 14 columns;
maximum punchout field size is 19 columns.
7. A field may be programmed to add into any or all accum-
ulators; punchout is limited to one accumulator per field.
8. Self-check fields may be adjacent. Self check and accumulate
operate in both punch and verify mode. However, self check
cannot be programmed in the same field as accumulate or left
9. Verify read control (11-0 code) must. not be programmed in
same column as auto skip (11) or auto dup (O) codes, nor in
any self-check programmed field.
10. Programs remain in storage until another program is read ;n
to replace the original program, or until mainline switch is
turned off, which resets programs 1-6 to blanks (equivalent
to 80 single-position fields, numeric shift).
