RE: It must be Monday, what have I done now?

Right.... Well... Yes... "adopt, adept and improvise" as someone said...

 I have to say I am a bit disappointed with IBM in this respect.. I had
hoped that the precompiler had a bit more knowledge about the scope of
variables. The raising of the compile-bar is something that can be
considered, however... Wouldn't that possibly introduce other errors
through the back-door?

I don't quite get your remark about changing the contents of a CONST
variable.. Where does this change take place then? In my view I am not
trying to change the variable, I am using that variable rather: passing
it on.

Don't tell me that the RPG Pre-compiler has absolutely no 

knowledge of 

global and local variables (there are other procedures present all 
using the same parameter names).

Sorry, but that's exactly the problem.  You can use local 
variables, but
they have to be unique or they have to be defined the same as 
any other
occurrences.

From the v5r3 manual:

Names in ILE RPG for iSeries applications that use SQL
Any valid ILE RPG for iSeries variable name can be used for a host
variable with the following restrictions. 
- Do not use host variable names or external entry names that 
begin with
the characters 'SQ', 'SQL', 'RDI', or 'DSN'. These names are reserved
for the database manager. 
- The length of host variable names is limited to 64. v The names of
host variables should be unique within the program. If the 
same name is
used for more than one variable and the data types are different, the
data type of the host variable is unpredictable.

From the v5r4 manual:

Names in ILE RPG applications that use SQL 
Any valid ILE RPG variable name can be used for a host 
variable with the
following restrictions. 
- Do not use host variable names or external entry names that 
begin with
the characters SQ, SQL, RDI, or DSN. These names are reserved for the
database manager. 
- The length of host variable names is limited to 64. v The names of
host variables must be unique within the program. The one exception is
that if a stand-alone field, parameter, or both, are defined 
exactly the
same as another stand-alone field, parameter, or both, the duplicated
name is accepted. 
- If a host variable is a duplicated name and does not belong to the
exceptional category mentioned in the previous item, but does have the
same type, the precompiler issues SQL0314 as a severity 11 
error instead
of its normal severity of 35. If you want to ignore these severity 11
errors, change the GENLVL parameter value on the CRTSQLRPGI command to
be 11 or higher.

Also, note that in your code you're attempting to use a CONST 
parm as a
host variable.  Even if you satisfied the SQL pre-compiler, the RPG
complier would complain since you'd be attempting to change 
the value of
a CONST parameter.

HTH,
