This program can be useful at sites with TU70/72 tape drives.
It is useful when the microcode in the DX20 appears to be hung in a
loop. By displaying the PC, it shows where the microcode is looping.
This might be indicative of some particular hardware problem. The
interpretation of the data should be left to the Field Service Rep.
The DEV number has been hard coded in this program. Hence in
order to use it at your site, you must change this value to reflect
the correct RH20 and then compile the program. A table of all
possible DEV codes for RH20 is given below. Select the number
corresponding to the RH20 assigned to the tape unit(the program or
CHANS can be used to find the correct RH20).
RH DEV Code

0 540
1 544
2 550
