3.7 LOADING ABSOLUTE FOCAP TAPE WITH THE LOADER/VERIFIER
The procedure for loading FOCAP format tape is similar to the steps outlined in paragraph 3.6
except for the starting address. The appropriate START address is obtained in the Loader/Verifier
program listing. To verify that the assembled program has been entered into memory correctly, the
tape is rewound and re-run after setting the appropriate PROGRAM SWITCHES. The tape to be
loaded must be positioned with the RUBOUTS/DELETES (all holes), that precede the load data,
positioned under the read head.
The function of the PROG RAM SWITCHES for loading and verifying either odd or even parity
tapes is as follows.
