No, that definitely wasn't it: this is of the "numeric code plus text
string" type, although it's interesting because it has multiple-length text
strings to trade off verbosity/helpfulness. It kind of reminds me of what
you get in ADVENT when you move to a place you have been before. You get
only a brief description, but if you type DESCRIBE you get the full monty.
That must have saved a lot of LA34/36 paper. :-)

a system. I can't pin it down with Dr. Google.
Something early from Digital Research?
Not quite what you describe, but a late DR OS had the following scheme.
http://bitsavers.org/pdf/digitalResearch/flexos/1073-2003_FlexOS_Users_Guid…
page 4, and 128 onwards:
The help level can have a value between 1 and 4. Your computer
manufacturer sets a default help level which you can override with DEFINE.
1 Displays the FlexOS function, the error source module, and the
return code.
2 Identifies the command and type of error in one sentence.
An example of a level 2 error message is "COPY: Write error."
3 Expands on the level 2 message and includes more specific
information.
An example of a level 3 message is "COPY: An error occurred writing
report.txt on a:".
4 Expands on the level 3 message and often suggests a possible
solution to the error.
An example of a level 4 message is "COPY: An error occurred writing
report.txt on a: The disk a: is full. You can erase unnecessary files to
free up space."
Where for scheme 1 it gave something like:
Error Code = 80137712
System Source Module = Pipe System
Function Returning the Error = write_data
Error Argument (long in HEX) = 123456
Error Argument (character string) = string
With only one of the last two lines printed, depending upon the function
in question.
