AFIT 020 Purpose:

Method:

Use:

AN

to

AFIT Key

Word Conversion

Prof Harling Nov 59

Given an '~ Master Tape, " to produce from it on

I~IT Relocatable Tape" of the same routine.

The AN key bits, which are placed, two per word, starting.

at location 4000, are packed together 38 per word, in key words which immediately follow the final word of the

routine.

1. Read 1n AFIT 016 Memory Dump, with origin at 6000.

Include the 'bptional features" at the en~ of the tape 2 • With B up, C down, D up, press START 3. This puts AFIT 015 Relocator on the outcoming tape.

3 • Read in the AN Master Tape to be converted.

4.

Read in the tape of AFIT 020 Conversion Routine, with origin at 5700.

5.

At location 5700, enter the Command Word -

+00 (N) • 0

+

00 (N) • 0

where N is a four digit octal number, giving the number of words in the routine on the AN master tape.

6.

Put Switch B up, C down, D down START

The AN key words are rearranged, and the routine f'rom the AN master tape is punched on the tape, with proper starting and ending arrangements. The word on the display panel gives initial and final addresses, end the nuriber of key words required for the routine.

7 · To verify the resulting tape, use the method given in section VII o~ the instructions for AFIT 016 Memory Dump.

Note that step (3) destroyed the AFIT relocator in memory but that it was reinserted by step

(4).

8.

Subsequent tapes are more easily produced from the first one obtained above, using the procedures of AFIT 016 Memory Dump.

9.

Both AFIT 020 Conversion Routine and MIT 016 Memory Dump are relocatSble. If either one is relocated to an origin different f'rom the one mentioned above, then the other must be advanced or set back in memory by an equal amount, for the procedures de,- scribed above to be valid.
