Inconsistent error output

From uv2

..\SRC\file.asm(167): error A9: SYNTAX ERROR

Note the file name as well as line number...informative.


From command line invocation of A51

ASSEMBLY COMPLETE. 0 WARNING(S), 1 ERROR(S)


No line number, much less a file name.

Is there any switch I can give a51.exe to produce a more informative error output?

TIA
