RUNNING THE DIAGNOSTICS
This section describes the System 6300 diagnostics and how to run
them.
TYPES OF DIAGNOSTICS
There are three types of System 6300 diagnostics— subtests,
tests, and test sequences.
Subtests and Tests
Subtests are simple checks.

subtests.
For example, the memory test comprises write 0's,
write l's, and write addresses subtests; and the parity test
consists of read and execute parity error subtests.
The specifications for both tests and subtests are pairs of
positive integers.

For a test, the pair consists of the test number and a zero.
example, in the following pairs:
8,5
8,0
the first pair specifies subtest 5 of test 8.
specifies test 8 (i.e., all subtests available for test 8).
default for the second value is zero.)
Test Sequences
Test sequences are predefined combinations of tests and subtests.
Some test sequences (for example, the parity test sequence)
consist of a single test.

Alphabetic characters denote test sequences.
For example, one subtest verifies
