The scanner Program Requests an Entry for Record Size

If you use the scanner program with the -s option but without an -i or -m option, and you receive the message:

please enter record size for this volume ('q' to quit) [xx] 

The number in the bracket [xx] is the entry from the last query.

The scanner command always rewinds the tape and reads the volume label to determine the block size. If the volume label is corrupted or unreadable, you see a message prompting you to enter the block size (in kilobytes).

Type in the block size; it must be an integer equal to or greater than 32. If you enter an integer that is less than 32, you receive the following message:

illegal record size (must be an integer >=32)
