…System 36 IDDU (Interactive Data Definition Utility)…

For those unfamiliar, the STRIDD command can give you initial access to IDDU. There are some interesting effects that are possible, though expertise is dwindling.

Look to see if the file contains a System 36 IDDU (Interactive Data Definition Utility) layout. If so then link the file using this utility and suddently you have a file layout. If you do not have a layout then make one using this utility and link the file and now you have the file layout that can be used for more than one field of information.

As well IDDU allows you to have multiple layouts for a file.

Non-DDS files actually has a filename for the whole record. Find your file’s fieldname using this command, which uses query/400:

runqry *n mylib/myfile

The fieldname to use in your query will be the heading-name (propably F00001..).

Now create your query making a resultfield : enter a resultfieldname, fx COMPCOD, and enter this expression

substr(F00001, 925, 3)

Then enter some selection in your query, and VOILA….

I hope thisworks for you

Thank you. The Company Code is ’001′. But who to create substring if there no fields names?
