If the bytes printed for verification begin with the ones you want to patch, enter the
patch in the following form:
I
hhhh hhhh hhhh .••
I
where:
hhhh hhhh hhhh . . .
are groups of four hexadecimal characters, separated by blanks
The length of the patch must be in the range of 1 to 128 bytes.
The entire patch must be within the boundaries of the sector you
specified. Note that the length of the patch does not have to
equal the value you specified for nnn (the byte verification
count).
If there are no errors, the patch
is
applied.
The utility responds with:
I
TROOlI DISKETTE PATCH COMPLETED
The utility issues the completion message which is followed by the prompt for the next
patch. The utility continues in this mode until you terminate it by pressing the LOAD
key.
THE OUTPUT YOU RECEIVE
HOW TO HANDLE ERRORS
6-12
GC34-0070
The output from this utility are prompt messages from the utility and the data for the
requested patch to diskette.
If a recoverable error occurs, the utility prints an appropriate error message and then
reissues the prompt. Recoverable errors are:
• Syntax error in your response to a prompt
• Device at specified device address not a diskette
• Sector address not a valid address for diskette
• Displacement not within the boundaries of the sector you specified
• Number of bytes to be displayed either exceeds 128 or less than or equal to zero
If an unrecoverable diskette I/O error occurs, the utility abnormally terminates. A
terminal error occurs when an I/O error prevents the utility from printing a message at
the operator station.
