[comp.sys.mac.hypercard] Error 1777 while importing data

mike@ronin.UUCP (11/18/87)

I have several PC-File data files which I am trying to import into
HyperCard.  The PC-File data file is a simple byte stream where
each block of 407 characters is a record.  There are no delimiters
between records or fields although each field is of a fixed length.

To do this, I wrote a script which opens the file and reads 407
characters.  I extract each individual field, trim trailing spaces,
make a new card, fill in the fields and repeat until the file
is completely read.

After adding about 2500 records, I get the message "Unexpected
error 1777 - Sorry".  After clicking Sorry, HyperCard just quits.
I then open the stack and it works until I try to compress it,
then I get the same error again.

Has anyone else seen this?  What is error 1777?  Have I reached
a limit on the number of cards in a stack?
