Hi, all:
I'm sorry to bug you again.
The following code is able to be built both with *Keil C51* and with *sdcc*.
However, *only* the .bin file built from *Keil C51* is working properly on
my board; the .bin file built from *sdcc* *doesn't work* on my board at all.
*A) code for Keil C51*

while(n!=0) P1_5=~P1_5,delay(m); * // am I right here?*
TR0=0;
}
}
So, can anybody help to explain why it is so? I can hear the music played
by the .bin file built from code A) for Keil C51. However, I'm not able to
hear the music played by the .bin file built from code B) for SDCC.
Thank you.
