Example
In this example, the PMW defined a text string of Press 8 Level 2 to
be written to the drive. This information was entered in ASCII text,
with the two characters of each word entered in opposite order. The
PMR returned a value of 261 in word 2, indicating a successful
write. In addition, it returned the text string in words 4 through 11.
If an error had occurred in the PMW, the PMR would have returned
an error code in word 3 of -32507.
