Re: Question on converting a VARLEN field to a CHAR field in a LF

The rename worked. Thank you.

IBM also got back to me and said that simply specifying the field in the LF
with the same name, a length example 100A and NO VARLEN, this makes the
field a field length field. Essentially, in the LF the field then becomes a
fixed length field whilst remaining a VARCHAR field in the physical file.

Thanks all.

Pretty sure that doing this would result in a file that is just read
only...

And if not then the VARCHAR field would end up with trailing spaces...

Sure.

In a logical with a different format name, define a fixed-length field

like

this:
A FHXF30 30 RENAME(FHXF)
A K FHXF30

This is a handy technique when you want to build a multi-format logical
over key fields (columns) of different lengths; this approach enables
powerful lookup and search applications. In SQL, you'd use the UNION ALL
clause and SQL happily resolves column size differences.

I have a OPM RPG program that I added a new file to. All the fields in

the

added file are variable length fields.



I need to chain to the file and update a flag in that file.



I cannot compile the program because OPM RPG does not support variable
length fields.



I compiled using CVTOPT(*VARCHAR) but that does not convert the key

fields.

Is there a way to redefine a variable length field as a char field in a
logical file?



Thanks
