About Using Wildcard and Backslash Characters in Filters
You can use wildcard characters (*) in report filters, but they are only allowed in filters that use the operators "==" or "!="; filters of any other type that contain "*" are in error, and you are prompted to re-type the filter. For example, you can use the wildcard in these filters:
&asm.mbr.name==part*
&asm.mbr.name==*my*, *your*
The first filter would match the strings "part," "part1," "part_A," and "partabcdefg." The second filter would match the strings "my," "this_is_my_assembly," "autonomy," "not_yours," and "your".
If you add a backslash (\) in the right-hand side of a filter (after the operator), the system reads the character after the backslash literally (as itself), not as a special character. You can then filter for an asterisk character. For example, &asm.mbr.name>=part\* matches strings that are alphanumerically greater than or equal to the string "part*".
The system interprets backslashes in report parameters or between string quotes literally as backslash characters. It interprets the parameter "&asm.\mbr.name" as a report symbol named "asm.\mbr.name" (an invalid name), and the filter:
&asm.mbr.name=="match this\”
matches only the string "match this\”.
It treats a backslash that is not in a report parameter, not enclosed by string quotes, and not followed by another character as a null string (" "). It interprets anything between two string quotes literally; the filter:
&asm.mbr.name<":\\***"
matches strings that are alphanumerically smaller than ":\\***". For filters created prior to Release 11.0 that contain the wildcard character, the system interprets the character literally (as an asterisk).

You should not use filters on the system parameter symbol "&rpt.index".
