While assembling the ESYMBOLS table you can get errors.
** ASMA044E Undefined symbol - ESYMBOLHDR
** ASMA435I Record nn in iprfx.iqual.CSIQOPTN($ESYMBOL)
Check the end of the assembler listing for error 'ASMA140W END record missing'
END instruction is missing at the end of the ESYMBOL table.
Check the ESYMBOL table and if the END is missing, correct it as follows:
***********************************************************************
* LAST INVOCATION - END THE TABLE GENERATION
*---------------------------------------------------------------------*
$ESYMBOL CALL=END
END
