RPG Field Scan

Scott,

For the scan function, just using the RPG SCAN opcode should be
sufficient.  For the uppercasing function, I would suggest using the
Convert Case (*PGM QLGCNVCS or ILE function QlgConvertCase) system API.
The APIs are documented in the System API Reference National Language
Support APIs chapter.  To convert the contents of field DATAIN from OPM
RPG (assuming you have already stripped of the '?') you could use:

     IREQCTL      DS
     I I            1                     B   1   40TYPE
     I I            0                     B   5   80CCSID
     I I            0                     B   9  120CASE
     I                                       13  22 RESERV
     IMISC        DS
     I I            11                    B   1   40LENGTH
     I I            0                     B   5   80BYTPRV
     I I            'Hello World'             9  33 DATAIN
     C                     MOVE *LOVAL    RESERV
     C                     CALL 'QLGCNVCS'
     C                     PARM           REQCTL
     C                     PARM           DATAIN
     C                     PARM           DATAOT 25
     C                     PARM           LENGTH
     C                     PARM           BYTPRV
     C           DATAIN    DSPLY
     C           DATAOT    DSPLY
     C                     MOVE '1'       *INLR
     C                     RETRN

Alternatively you could use the RPG XLATE opcode to perform uppercasing,
but using the API provides valid uppercasing in all national languages
supported by the AS/400 (the CCSID of 0 in REQCTL) without you having
to be concerned with the language currently in use.
