RE: Fetching into different host variable types

What I am suspecting the problem is
    -- The host variable was specified in dynamic SQL. Host variables are
not valid in dynamic SQL.

Which would mean changing from:
        FetchStmt='Fetch C1 into :' + %trim(aKeyFld(kaelem)) + ', :' +
                  %trim(aFld(faelem)) + ', :' + %trim(aResultFld(faelem));
...
     C/EXEC SQL
     C+ Prepare FetchStmt from :FetchStmt
     C/END-EXEC
     C                   if        sqlcod<>0
...
     C/EXEC SQL
     C+ Execute FetchStmt
     C/END-EXEC
...

To:
        FetchStmt='Fetch C1 into ?,?,?';
...
     C/EXEC SQL
     C+ Prepare FetchStmt from :FetchStmt
     C/END-EXEC
     C                   if        sqlcod<>0
...
     C/EXEC SQL
     C+ Execute FetchStmt using :packedk, :alpha, :alphar
     C/END-EXEC
...

If this is my problem, then help me understand to do dynamically select the
variable types on the Execute FetchStmt using...
For example, the next time I run this program it may be :AlphaK, :Packed,
:PackedR
