There was a thread on conversion in september 2005. At that time Elvis advised 
me to play with iconv function.
I now tried to find the test program I wrote that time, but failed :-(
I recall, that I made a cycle on <toCcsid.CcsidNbr> and the results where 
funny. There where VERY FEW values, that the function was ready to convert from 
00037. So it is not the problem of programming, but rather the combination of 
"TO" and "FROM".

That time I found the solution to my problem elsewhere, but I can tell you for 
sure, that you should not be surprised by this error message. Maybe someone 
will tell what causes it.
Maybe the answer is in library QUSRSYS in files of type *TBL.
