Hex conversion

HI, I need to convert a string of hex into decimal but I can't seem to figure it out. A string something like

$0,$36,$EE,$80

Needs to be seen as

$0036EE80

And that one hex value converted to decimal or even ASCII, something I can perform some math on and then display ultimately as decimal.

Any ideas much appreciated.

    Something like this:

    DEFINE_VARIABLE

VOLATILE CHAR cHexString[] = {$0,$36,$EE,$80}
VOLATILE LONG lDecimal

DEFINE_FUNCTION LONG fnHex(CHAR cHexData[]) 
{
    STACK_VAR VOLATILE CHAR cResult[100]
    STACK_VAR VOLATILE INTEGER i
    FOR(i = 1 ;i<=LENGTH_ARRAY(cHexData); i++) 
    {
    cResult = "cResult,FORMAT('%02X',cHexData[i])"
    }
    SEND_STRING 0, cResult
    RETURN HEXTOI(cResult)
}


lDecimal = fnHex(cHexString)

    Thanks I'll see if I can make that work. The thing is the hex string can change at any time so I have to allow for any possibility of 4 bytes.

    As long as the four bytes represent a valid number, it'l work. Good luck.
