This i what I find on the net:

"Case Flag
The case flag, DM_DEFAULT_CASE, determines how Prolifics's database drivers use case when searching for Prolifics variables for holding SELECT results. This setting is used when comparing ORACLE column names to either a Prolifics variable name or to a column name in a DBMS ALIAS statement.

ORACLE is case insensitive. Regardless of the case in a SQL statement, ORACLE creates all database objects-tables, views, columns, etc.-with upper case names. For ORACLE, the DM_DEFAULT_CASE setting is treated as DM_FORCE_TO_LOWER_CASE. This means that Prolifics attempts to match ORACLE column names to lower case Prolifics variables when processing SELECT results. If your application is using this default, use lower case names when creating Prolifics variables.

The case setting can be changed. If you wish to use upper case Prolifics variable names, use the u option in the makevars file for the DM_FORCE_TO_UPPER_CASE flag.

ORA_INIT=u
If you edit makevars.ora, you must remake your Prolifics executables. "

I couldn't find makevars.ora file. I've NT and Oracle 8.1.7
