hello there.
i got that program kb.asm
but when i tried to compile it using keil.it gave me many errors.first of all
it didn't get .equ .flag and .db directives.Keil says that its syntax error.
how can i get over this? can some one test this program and convert it into hex for 8051(as i m not a good programmer) ?
