Yes of course, you can use the SQL Substr-Function in every UPDATE 
statement, in the SET-clause on the _RIGHT_ side of the equal sign. That
means, that you can move the Substr to any string field, but you could NOT
use the Substr as the target (like in RPG/IV)!

For the ones, who are using a german language OS/400, use the Substr-
function as follows:

          xxx = substr(yyy,_1,_10)

Where the underscores (_) are blanks! The blanks following the commas are
required by any german SQL (and by Query too)!!

I hope this could be helpfull!
