This, IMO, really pushes me toward Walden's solution of using SQL. That's a really nice use of the update statement. Tim, if you don't have the SQL licensed product installed, you can still do this by creating a query management (*QMQRY) and then execute STRQMQRY from a CL or whatever. Here's how to do it so that you don't even have to hard-code the file and field names:

1. Create a source file called QQMQRYSRC, record length 91 (really!).

2. Add a member to QQMQRYSRC, say UPPER.

3. Put the following statement in the source member:

update &file set &field = upper(&field) where &field <> upper(&field)

This uses replacement variables &file and &field. These are what takes away the hard-coding. Later you'll execute STRQMQRY and specify values for these variables. Anything you put there simply replaces the variable. Therefore, you can even put in a qualified filename.

4. Create the *QMQRY:

CRTQMQRY QMQRY(somelib/UPPER) SRCFILE(somelib/QQMQRYSRC) SRCMBR(UPPER)

5. Assuming an appropriate library list, run the statement with

STRQMQRY QMQRY(UPPER) SETVAR((FILE filename) (FIELD fieldname))

6. You can use this in a CL, which could even be the command processing program for something like

CVT2UPR FILE(filename) FIELD(fieldname)

In this case, the STRQMQRY command could be

STRQMQRY QMQRY(UPPER) SETVAR((FILE &FILE) (FIELD &FIELD))

Good luck
