Abstract: This is a package of three programs which extend the input/

output capabilities of system, user, and 8K FORTRAN programs in

OS/8 to include the TC58 magnetic tape. The first is a TC58 device

handler (2 page, non file-structured) that includes six special function

calls and can use any desired tape recording format. The second is a set

of nine SABR subroutines (FORTRAN-callable) that provide formatted

and unformatted tape input/output and special functions (endfile, spac-

ing forward and reverse, rewind). The third is a SABR main program

which allows the operator to position and write EOF marks on a tape,

dump records in octal, and write test data.

Restrictions: No EOF written to close tape files. Does not use

TCS8 continuous mode.
