plsql question
I am trying to write a plsql routine that will delete a range of
characters based on their octal or hexadecimal values. Something like
the 'tr' shell command will do:
cat file| tr -d ['\177'-'\377']
Can't seem to figure this one out.
Pointers would be appreciated.

Would the string functions to_hex(), translate(), replace() and friends
work for you?
