16F872 and LCD

[skimask]

Give this a shot:

@ DEVICE PIC16F872, HS_OSC, WDT_OFF, PWRT_ON, LVP_OFF, PROTECT_OFF
DEFINE OSC 20
DEFINE LCD_COMMANDUS 3000
DEFINE LCD_DATAUS 250
temperature var word : count_remain var byte : count_per_c var byte
dq var portb.2 : ADCON1 = 7 : pause 1000 : lcdout $fe , 1
mainloop: OWOut DQ , 1 , [ $CC , $44 ]
waitloop: OWIn DQ, 4, [count_remain]	 : If count_remain = 0 Then waitloop
owout dq, 1, [$cc,$be]
owin dq , 0 , [ temperature.lowbyte , temperature.highbyte , skip 4 , count_remain , count_per_c ]
temperature = ( ( ( temperature >> 1 ) * 100 ) - 25 ) + ( ( ( count_per_c - count_remain ) * 100 ) / count_per_c )
Lcdout $fe , $80 , DEC3 ( temperature / 100 ) , "." , DEC2 temperature, " C"
temperature = ( temperature * / 461 ) + 3200
Lcdout $fe , $c0 , DEC3 ( temperature / 100 ) , "." , DEC2 temperature , " F"
Pause 1000 : goto mainloop

Also, in your original code, you show:
define OSC 20

Put all DEFINE's in upper case. It's a bit weird like that.
Your original code was probably still compiled as if it were for a 4 Mhz oscillator, even though you had 'define OSC 20'.
