Abstract: LIB8X is a FORTRAN II library which makes use of Mode

A EAE instructions, and as a result, executes programs approximately

twice as fast as standard OS/8 FORTRAN II. The format of the floating

point word was changed to a 23 bit mantissa which causes a reduction in

precision. However, the new routines have a reasonable rounding algorithm

and by empirical tests maintain better accuracy in interative

calculations than the 27 bit package. New subroutines EOF, on device 4;

RESET, implements DECODE; LBYT & SBYT for byte manipulation.

Note: Old Data must be converted.
