Long / short press button...but reading ADC

[fratello]

Hi !
I need again for your help ! I tried to build one simple schematic ; I used 12F675 for reading ADC. Works fine.
But ... I have no clue how to "find" if the button is pressed short (let's say under 1 sec) or long ( > 1 sec) ...for having different commands.
Can someone point me into the right direction ?
Thanks in advance ! Have a nice day and weekend !

@ __config _XT_OSC & _WDT_OFF & _PWRTE_ON & _MCLRE_ON & _BODEN_ON 

DEFINE OSC  4

CMCON    = 7
TRISIO   = %00001001
INTCON   = 0 
IOC      = 0
GPIO     = 0
ANSEL    = %00110001
ADCON0.7 = 1

DataW    var WORD		' Just a WORD Temporary working variable

Main:
ADCON0 = %10000001
	Pauseus 50		' Wait for channel to setup
	ADCON0.1 = 1		' Start conversion
	While ADCON0.1=1:Wend	' Wait for conversion
DataW.HighByte=ADRESH		' Read variable from ADC and save
DataW.LowByte=ADRESL

If DataW > 0 AND DataW < 1023 then GPIO.2 = 1
Pause 1000
GPIO.2 = 0
Goto Main
