Something like this is where LOOKUP2 comes in handy.
Code:
    @ DEVICE PIC16F88, WDT_OFF,INTRC_OSC,MCLR_OFF,BOD_ON,LVP_OFF,PWRT_ON,PROTECT_OFF

    DEFINE  OSC 8
    DEFINE  NO_CLRWDT 1
    OSCCON  = %01110000 ' 8MHz
    CMCON   = 7	        ' disable analog comparators
    ANSEL   = 0         ' disable A/D module, all digital
    X VAR WORD
    Index VAR BYTE

    LED VAR PORTB.0    
    TRISA = %00111100   ' RA2 to RA5 inputs for DIP switch
    PORTB   = 0
    TRISB   = %11111110 ' RB0 for LED
    OPTION_REG = %11111111
    
    WHILE OSCCON.2 = 0  ' wait for internal osc stable before moving on
    WEND
    
Main:
    Index = (PORTA >> 2) & $0F ' Read DIP switch AND mask result
    LOOKUP2 Index,[200,300,400,500,600,700,800,900,1000,2000,_
    3000,4000,5000,6000,7000,8000],X
    HIGH LED
    PAUSE X
    LOW LED
    PAUSE X
    GOTO Main

    END
