ASMA999U

Assembly terminated - SYNAD Exit taken - Permanent I/O error
on xxxxxxx data set
Explanation
The assembly was stopped because of a permanent I/O error on the
data set indicated in the message. This is typically caused by a
machine or an operating system error. The assembly can generally be
rerun successfully. This message also appears on the console output
device.

System action
A special abnormal termination dump (High Level Assembler interrupt
and diagnostic dump) follows the message. Depending on where the error
occurred, the assembly listing up to the bad statement might also
be produced. The dump generally indicates which statement caused termination.
It also might include contents of the assembler registers and work
areas and other status information for use by IBM or your assembler
maintenance programmers in determining the cause of the termination.

Programmer response
If the I/O error is on SYSIN or SYSLIB, you might have concatenated
the input or library data sets incorrectly. Make sure that all input
or library data sets have the same device class (all DASD or all tape).
Also check that file attributes such as DSORG, RECFM, LRECL, and BLKSIZE
have been correctly specified.

If the I/O error is on SYSUT1, check that SYSUT1 is allocated to
a single volume—the assembler does not support a multivolume
work file.

Reassemble the program; it might assemble correctly. If it does
not reassemble without error, save the abnormal termination dump,
the assembly listing (if one was produced), and the input sources,
and contact IBM for support. Also, if the program assembles correctly,
submit a copy of the listing and input sources of the correct assembly.
