well this may be one reason... it's looping but doing nothing in-between
I think that is ok, it loops until tmr0 interrupts on overflow.

I have never used ON INTERRUPT, but I see some mistakes probably from cut and paste. ON INTERRUPT should be on a separate line, not in the configurations

OPTION_REG and INTCON need % in front of the binary numbers

enable at the end of the code will never happen, since resume returns us to the main program.

What else?

Code:
@ __config _INTRC_OSC_NOCLKOUT & _WDT_OFF & _PWRTE_ON & _MCLRE_OFF &_BODEN_ON & _LVP_OFF & _DATA_CP_OFFON INTERRUPT GoTo VAIL  
OPTION_REG=000001    
define OSC 4
CMCON=7
INTCON=100000 
trisa=0
trisb=0
porta=0
portb=0
SYMBOL SES=PORTA.1
t var word
a1 var byte
a var byte
x var byte
