If Lawson is using CPYTOSTMF or CPYTOIMPF to generate the .prt files they're
probably leaving the parameter default for stream file code page
(STMFCODPAG).  The default parameter value is *STMF, which will create .prt
files with the same code page as the source object (EBCDIC) *unless* the
.prt file already exists.  If the .prt file already exists as an ASCII file
it will be recreated (or appended if the STMFOPT parm is *ADD) as ASCII.

You might try to verify this by scanning Lawson's environment source for the
CPYTOSTMF and CPYTOIMPF commands.

You might be able to modify Lawson's environment program(s) to hard code a
code page of *PCASCII or *STDASCII on these commands.  I have no idea what
Lawson uses these files for (other than wasting a lot of disk), so I don't
know what functions might be expecting EBCDIC files and what you might screw
up.

You can visually check the character set of the file by performing a WRKLNK
and checking attributes.  I have no idea how to retrieve it
programmatically.  Maybe there's an API?
