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

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.
