IBM 5100 User Manual

Call: This function allows you to load the tape read test
into read/write storage for execution, and allows you to
execute the op code, read/write storage, and ROS test
routines from executable
ROS. Call also provides tape
copy
and storage dump functions.
Once DCP1 diagnostic mode is entered, use the following
keying
sequence to use the call function:
1.
Press C.
2. Hold the CMD key and press a numeric key to load
the call routines.
Use the numeric keyboard for
entering digits 0-9.
3. Press EXECUTE.
Each call routine is identified by a digit (0·9) preceded by
CMD.
The following list
shows the format for all routines and
their names:

Tape Read Tests - CMD 0 and CMD 1
CMDO
C TAPE TEST
EXEC -
This routine tests the read function on the tape unit. It
performs the same tests as the CMD 1 routine except
the forward motion and reverse motion test. Therefore,
this test provides a faster access
to the DCP2 program.
Return
to DCP1 diagnostic mode by holding CMD and
pressing ATTN. Exit DCP1 diagnostic mode by pressing
RESTART.
CMD 1
C TAPE DrAG
EXEC -
This routine tests the read function on the tape unit. It
also tests the forward and reverse motion. This test
provides access
to the DCP2 program. Return to DCP1
diagnostic mode by holding CMD and pressing ATTN.
Exit from
DCP1 diagnostic mode by pressing RESTART.
