PARAMETERS

HRM
maxseg=maximum segment nwnber to be tested (Jefaul t=3)
minseg=minimum segment number to be tested (default=O)
DESCRIPTION
NEWlVIEM1 does a random data test on the memory segments given
in the par ameter s . Eac h memor y segmen t i s
64 K
byte.3.
Tl1
e
test gets repeated
n
times, where n=#REPS in the test line.
NEWMEM1 must relocate the test code if
3egme~t
J
is
t23t2i.
If minseg=maxseg=O, the code is relocated to
segme~t
1
and
the test runs from segment
1.
If minseg=O and maxseg>O, the
code rotates through the segments to be tested. On the first
lap, the code is in segment 0; on the second lap, it is in
segment
1,
and so on. On each lap all the segments from
0
to
maxseg are tested except, of course, the segment where the
code resides currently. This implies that at least
tAO
repetitions must be done for thorough testing.
The test fills each segment with random data, then reads it
back for verification.
ERROR MESSAGES
If the data found in a memory location is not correct, a
RANDOM TEST ERROR message appears. It gives the address
where the error occurred, what the data should be (DATA=),
and what was found In memory (BAD=),.
All NEWMEM1 errors are reported as HARD errors.
LAP SUMMARY
After each repetition of NEWMEM1, the last 19 error messages
are displayed. The errors are accumulated from one repeti-
tion to the next.
