***********Next, program flash************
CALL GPGMJ ;Program flash from buffer.
LACL ERROR ;Check for program error.
BCND prg_error,neq;If error then clear ACC.
B prg_done ;Else, No errors programming.
prg_error:
**********************************************************
** If here, then an error occurred during programming. **
** In an actual application, the system takes some **
