SUMMARY

The directory BIT contains three programs and one subroutine.
The programs SBIT, CBIT and ?BIT all operate on one bit in a hex
string (binary integer).  Because these programs were originally
created to manipulate a hex string that contained flags used in
an application they function differently than the built-in binary
integer commands.  Unlike the usual commands found in the BASE
menu on the 48, which only operate on hex strings that are 16
nibbles long, these programs will operate on a hex string of any
length.


SBIT     hex string, real  ->   hex string
               sets one bit in a hex string

CBIT   hex string, real  ->  hex string
             clears one bit in a hex string

?BIT   hex string  real  ->  real (0 or 1)
             tests one bit in a hex string
