We have solved this problem indirect by defining new number codes
for usersyms.

http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _html/dbase/download/icgsym_n.tar.gz

icgsym_n,/symhelp ; shows all symbols

All usersyms are defined in this routines. e.g. 208 is a filled circle

If now a number gt 7 ne 10 is used it is a user defined symbol.
