You can specify the maximum record size for a Btrieve file by setting an attribute in the Xfh2btr configuration file as follows:
BTRMAXREC:nnnn
where nnnn is a byte value. You should set BTRMAXREC to the record size of the largest record to be accessed. If you do not set BTRMAXREC, the default value of 32 Kilobytes is used.
