Richard,
We've done a lot of large HC to Rev conversions and have run into the
same problem.
1. Make sure the original HC stack has been compacted, several times
2. Strip all NULLs before import. These can get into the data if a
user has pasted text into the HC fields from Word or some other
programs. It appears that Rev removes all data between the NULLs.
3. Don't use Rev cards for a large number of records, it just won't
handle the information in this format as well as HC did. Move to a
database - or use a text file for the data.
4. Put in some wait states ("wait 0 seconds") in your import routine
to let the computer "catch up" and finish processing current
information before continuing.
5. Don't try to view the information in a Rev field. This will
truncate any information beyond approx 64,000 characters in a line.
If you view it in a field and then put the field back into the DB,
all of the truncated info will be lost.

I have been able to convert most of my stacks flawlessly, with one
exception. In the late 1990s I produced a stack for a research
project in Russian which contained 119,000 cards (sic!). It has
become necessary to reactivate this stack, and to convert it to
Revolution Enterprise 4.5 I have followed the prescribed Revolution
procedure. After conversion, all the functions I had built into the
stack work as they should, but the converted stack contains only
28,005 cards.
Is there a built-in limit on how many cards a conversion can
accommodate?
Is there a work-around?
Any advice appreciated.
Hopefully,
Richard Pierce
