This article was previously published under Q63901 SUMMARY
On page 323 of the "Microsoft Basic 7.0: Language Reference" manual,
the example for the SEEK statement (on the 6th line from the bottom)
incorrectly shows that the process for backing up a file is as
follows:
SEEK #1, SEEK(1) - LEN(RecordVar)
This statement is the correct method for backing up one record
position in a binary file. In a binary file, the SEEK function refers
to a byte in the file. Therefore, to move forward or backward a
record, you would increment or decrement by the number of bytes in
each record of the file.
However, because the file in the SEEK example on page 323 is a RANDOM
access file, a SEEK function refers to each record in the file, not to
each byte in the file. Thus, the statement should be corrected to read
as follows:
SEEK #1, SEEK(1) - 1
