Sorry for the late response. I have been away for awhile. I have uploaded the following to the URLs shown:
http://wikisend.com/download/53466 vistatil.bas (the application displaying a page of two records with fields that describe a book)
http://wikisend.com/download/83063 title.hdg (headings of the above fields)
http://wikisend.com/download/22972 title.dat (data that is displayed in the above fields)
I have a program by which I can extract data from the above records for use in Excel
so want to ensure that program can still do so after modifying fields on the records for the title page. Perhaps that program will need to be tweaked to do so.
I have done more thinking about the modifications to the book title record that I would like.
When you run the above files you will note in vistatil.bas there is a page of two 256 byte records that displays fields to insert data on a given book title. Fields on the first record are Title, Author, Description. At the start of the second record is a field that continues description of the book. The last part of this record carries fields whose data is accessed for reports by various other programs and thus these fields must remain in their present locations. The first part of the second record is therefore where space is available to place new field headings.
When browsing this page of two records the cursor, after moving through the fields on the first record, now lands at the start of the second record. If the programming is substantially simpler, new headings could begin at the start of the second record and follow in sequence as the cursor scrolls from one field to the next until it begins scrolling though the existing fields. But if not a lot simpler to have the new fields start at the beginning of the second record, then I'd like to preserve what I can of the space at the beginning of the second record for the continuation of the book description and have the new fields be inserted in front of the existing ones that are toward the end of the second record.
New fields would include the headings
YR: (needs 2 spaces to insert year data),
OP: (needs 4 digits to insert month and year),
COND: (needs 1 space to insert single letter to describe condition, such as new, used, scuffed, rare), AGE: (needs 5 spaces to insert age group, such as kind, el-hi, 10-15, adult).
NEW1 (a field for future use, as I can change name. say 2 digits)
NEW2 ( a field for future use, as I can change name, say 10 digits)
The order of these fields is not important.
You may find it convenient to have the names, locations, and lengths of the existing fields on the two records Here they are (from some very old notes so maybe a little off toward the end):

Thanks for being willing to take a look at this for me.
