Operating Procedures; Store A Program (Program Load) - IBM 129 Description

Operating Procedures
POWER ON
Setting the mainline switch to ON resets (erases) all stored
programs and data, and selects program level 0 regardless of
PROGRAM MODE dial setting.
Program level 0 control is 80 single-position fields (alpha
shift). Program levels 1-6, at this time, are controlled as 80
single-position fields (numeric shift). Program selection is
possible, although program levels 1-6 are identical, until
programs are read into program storage.
Punching and verifying can be done under program level 0
or 1-6 control. However, the first operation normally
performed, after power is turned on, is to store the
programs desired in program levels 1-6.
New program cards may be punched before programs are
loaded by using the "Punch a Card" procedure.
STORE A PROGRAM (Program Load)
The desired program cards must be read into program
storage to allow program control to be active during
keying:
1. Operate CLEAR switch if card bed is not clear.
2. Set AUTO SKIP/DUP to OFF.

3. Set PROGRAM MODE to desired program level (1-6).
4. Insert program card at punch/read station (punch or
verify mode), or feed card one cycle from the hopper to
the pre-register position (punch mode). Card must not
be registered.
5. Press READ pushbutton.
Repeat steps 3-5 for each program card to be stored. Each
program load operation reads program card data into
selected program storage level, stacks card in stacker, and
sets machine to column 01 of that program level. Programs
remain in storage until a new program is read into that
program level or until a power off/on operation resets
them.
Note: In punch mode, up to six program cards may be
placed in hopper, fed singly, and program loaded by
repeating steps· 3-5. Then set PROGRAM MODE dial,
manually select desired program level, and set PUNCH/
VERIFY switch to PUNCH or VERIFY to start operation.
