Hallo Ralf,
da habe ich dies dazu gefunden:
DESCRIPTION OF PROBLEM FIXED FOR APAR SE19561 :
-----------------------------------------------
The parsing of a FROMFILE on a CPYFRMIMPF command to find a
valid record delimiter can result in MCH0601 messages when the
record delimiter is not found within an expected range of
FROMFILE data. This typically happens when a record delimiter
is encountered within a pair of string delimiters or after a
dangling string delimiter.

CORRECTION FOR APAR SE19561 :
-----------------------------
Message CPF2845 with undocumented reason code 98 is now issued
and the CPYFRMIMPF processing is stopped when a valid record
delimiter is not found within an expected range of FROMFILE
data.

CIRCUMVENTION FOR APAR SE19561 :
--------------------------------
None.
