ASMA152S

External symbol too long or unacceptable character - xxxxxxxx
Explanation
One of the following errors has occurred: 
An external symbol is longer than eight characters, or the limit
is 63 characters when the GOFF/XOBJECT option is in effect, or contains
a bad character. An external symbol might be the name of a CSECT,
RSECT, START, DXD, AMODE, RMODE, or COM statement, or the operand
of an ENTRY, EXTRN, or WXTRN statement or a Q-type or V-type address
constant.
The operand of an ENTRY, EXTRN, or WXTRN statement or a Q-type
or V-type address constant is an expression instead of a single term,
or contains a bad character.
A class name in a CATTR statement is longer than 16 characters,
or contains a bad character.

System action
The symbol does not appear in the external symbol dictionary. If
the error is in the name field, an attempt is made to process the
statement as unnamed. If the error is in the operand field, the bad
operand is ignored and, if possible, the following operands are processed.
A bad constant assembles as zero.

Programmer response
Supply a shorter name or replace the expression with a symbol.
