How do I put a comma in a decimal number and place it on the screen of the LCD?

Adcin 0, an0  'read AN0 and write value to AN0

    Lcdcmdout LcdLine1Pos(12)
    Lcdout #an0

    Lcdcmdout LcdLine1Pos(1)
    Lcdout "Volt"
        pc1 = an0 * 6 / 10
            Lcdcmdout LcdLine1Pos(6)
    Lcdout #pc1
        WaitMs 250
    Lcdcmdout LcdClear

Goto main
End

number(5) as byte

number(0) = value / 1000 MOD 10 + 48
number(1) = ","
number(2) = value /100 MOD 10 + 48
number(3) = value /10 MOD 10 + 48
number(4) = value MOD 10 + 48
number(5) = 0

for x = 0 to 5
   Lcdout #number(x)
next x

main:  'endless loop

Adcin 0, an0  'read AN0 and write value to AN0

    Lcdcmdout LcdLine2Pos(12)  'write from position 12
    Lcdout #an0  'just to see on the screen what the digital number is!

    Lcdcmdout LcdLine1Pos(1)  'write from first position
    Lcdout "Volt"  'write the word "volt" on the screen!
   
        pc0 = an0 * 594 / 100000 Mod 10
    Lcdcmdout LcdLine1Pos(6)
    Lcdout #pc0

        pc1 = an0 * 594 / 10000 Mod 10
    Lcdcmdout LcdLine1Pos(7)
    Lcdout #pc1

    Lcdcmdout LcdLine1Pos(8)
    Lcdout ","

        pc2 = an0 * 594 / 1000 Mod 10
    Lcdcmdout LcdLine1Pos(9)
    Lcdout #pc2

Goto main
End
