Actually, I'm looking for someone to tell me something about how to define a symbol in z/OS assember. (z390 emulator)
You need to be more precise -- do you want to define a MACRO symbol, a variable, a constant, a label for an instruction, or what?how to define a symbol in z/OS assember
And this is a HELP forum -- not a TEACHING forum. If you want instruction, you would vastly be better off getting it from a school or even by reading a book rather than posting questions here.

Explanation: The error occurred during processing of an OPEN macro instruction. This system completion code is accompanied by message IEC141I. Refer to the explanation of message IEC141I for complete information about the task that was ended and for an explanation of the return code in register 15 (which is provided in the IEC141I message text).
Application Programmer Response: Respond as indicated for message IEC141I.
System Programmer Response: If the error recurs and the program is not in error, look at the messages in the job log for more information. Search problem reporting data bases for a fix for the problem. If no fix exists, contact the IBM Support Center. Provide the JCL and the program listing for the job.

If your continuation line does not start in column 16, you will get an error message -- such as2.2.2 Continuation Lines
To continue a statement on another line, follow these rules:
Enter a non-space character in the continuation-indicator field (column 72). This non-space character must not be part of the statement coding. When more than one continuation line is needed, enter a non-space character in column 72 of each line that is to be continued.
Continue the statement on the next line, starting in the continue column (column 16). Columns to the left of the continue column must be spaces. Comment statements may be continued after column 16.
continuation line < 16 characters -
means DATAIN was not defined. Whether or not it actually appears in your source code does not matter -- the assembler is telling you that you do not have a valid defintiion for it (maybe because of the continuation line errors preventing it from being recognized as a symbol).symbol not defined DATAIN
Invalid character in opcode is most likely -- and this is only a guess -- that either your opcode does not start in column 10, or your operands start in column 15 or earlier. Assembler can be extremely picky about the columns things appear in.
(remember, no doing work for me).
