Int 21H Function 23H
   Summary  Notes  Back
──────────────────────────────────────────────────────────────────────────────
 
▀ An appropriate value must be placed in the FCB record size field (off-
  set 0EH) before calling this function. There is no default record size
  for this function. Compare with the FCB-related open and create func-
  tions (Int 21H Functions 0FH and 16H), which initialize the FCB for a
  default record size of 128 bytes.
 
▀ The record size field can be set to 1 to find the size of the file in
  bytes.
 
▀ Because record numbers are zero based, this function can be used to
  position the FCB's file pointer to the end of file.
