in ORACLE, field names or table names can begin with an underscore, but they must be enclosed in double quotation marks. It's a bit weird to try not to start with an underscore.

example:

SQL > create table T1 (_ col1 number,_col2 number);

create table T1 (_ col1 number,_col2 number)

invalid ORA-00911: characters

SQL > create table T1 ("_ col1" number, "_ col2" number);

Table created

Previous: Is it because the array is treated as a pointer that the cPP array does not report an error when it is out of bounds?
