While assembling the ESYMBOLS table you can get errors.
** ASMA044E Undefined symbol - ESYMBOLHDR
** ASMA435I Record nn in hlq.slq.CSIQOPTN($ESYMBOL) on volume: volser.
Check the end of the assembler listing and check for error 'ASMA140W END record missing'
END instruction is missing to end the assembly of the table.
Check the ESYMBOL table, if the END is missing, correct is as follows:
***********************************************************************
* LAST INVOCATION - END THE TABLE GENERATION
*---------------------------------------------------------------------*
$ESYMBOL CALL=END
END
For any other assembly error, check that the right CSIQOPTN is allocated to ddname SYSLIB.
Otherwise, submit your case to CA Support.
