CPYSPLF generates "+" print char

 
Hello
 
After a change of our mainframe printing software, we suffer the
following problem on our customer's AS/400 (V4.R3.M0 L00):
 
The output is sent to the AS/400 spool and looks still correct.
 
Our customer then uses the CPYSPLF function to convert the
spool file for further processing. He uses the option CTLCHAR = *FCFC
 
On the results of CPYSPLF we see repeatedly the following:
 
***********************************************************************
0   00401000   Warenaufwand Diverse                  45,60-   0,00
               Total War                                                <==
+                       enwert                       45,60-   0,00      <== 
***********************************************************************

... instead of:


***********************************************************************
0   00401000   Warenaufwand Diverse                  45,60-   0,00
               Total Warenwert                       45,60-   0,00      <== 
***********************************************************************

Does anybody know, under which circumstances the CPYSPLF will make
the two lines with the + print control character (suppress space) ?
 
Thanks for your help
 
Kind regards
