- LPC
LOAD PC - Load PC with address
Example LPC FFF(CR)
- LUP
LOAD MICROPROCESSOR - Loads an ascii file with an "ADX or CDX" extension
into the CRAM of the DX20'S micro processor starting at location 0.
"CDX" extensions are used when sub files(.ADX) are combined together
to form one file. "ADX" extensions can be used for single files.
Example---LUP FOO,FO1(CR)
Where "FOO" is the subfile(.ADX) within the FO1 file(.CDX)
or
LUP FOO(CR)

Example RCI 4(CR)
- RCR
READ CRAM - Read CRAM data from loaction 40.
Example RCR 40(CR)
- RCA
READ A RANGE OF CRAM - Read CRAM locations 0 through F.
Example RCA 0,F(CR)
- RDA
READ RANGE OF DRIVE ADDRESSES - Read drive registers from 0 to 1F.
Example RDA 0,1F(CR)
- RDP
READ DATA PATH REGISTER - Read data path interface register 4.
Example RDP 4(CR)
- RDR
READ DRIVE REGISTER - Read drive register 4 from Massbus.

- DEVICE
Type HELP DEVICE device-type for device description.
- EVENT
Event Flag 1 (set) - Prevents functional microcode from running internal
diagnostics.
Event Flag 2 (set) - Bypasses end of tape test.
Event Flag 3 (set) - Invokes the Console Control Program.
Event Flag 4 (set) - Bypasses data security erase test.
- HELP
This program will detect failures in the following components of the DX20
magnetic tape subsystem:
DX20
TX01/02
TU70/72
In addition a console control package is provided to allow the user
to manually control the DX20 microprocessor and access all DX20
registers.
For information on the console control program type HELP EVMCC CCP
- QUICK
The QUICK flag causes the end of tape test and the data security erase
tests to be bypassed.
- SECTION
- DEFAULT
Runs all the tests in this diagnostic.
- SELECT
To select the DX20 for testing use the following command.
DS> SELECT ALL
- SUMMARY
This program provides a summary report of the total number of read
and write operations performed. A summary of the total number of read,
write, and writecheck errors. And a summary of the per pass total
number of read, write and writecheck errors.
