a call to delay subroutine results infinite loop

I'm using keil uvision 4 and learning programming for AT89s52 , I'm using 12MHZ frequency.

I have written a subroutine for a delay of 10 micro sec which is in another file called DELAY.ASM and made a call from DELAYCALL.ASM to it, but the call results in an infinite loop.I just dont have a clue why this behaviour, please help?clarify this phenomenon

DELAY.ASM

DELAYS_A SEGMENT CODE
RSEG DELAYS_A

DELAY10MICROSEC:
NOP
NOP
NOP
NOP
NOP
NOP
NOP
NOP
RET

DELAYCALL.ASM

$INCLUDE(DELAY.ASM)

CSEG AT 0

ACALL DELAY10MICROSEC

END

but the code was not intended to do that

And how did you tell the code what you intended to happen instead? In other words, what did you believe the subroutine would be returning to, and what was going to happen there?
