Here is a quick method that can be used for converting Decimal values to Hexadecimal values using PHP EXECUTE and the dechex php command:

C_TEXT($0;$result) C_LONGINT($1) C_BOOLEAN($phpOK) If (Count parameters=1)  $phpOK:=PHP Execute("";"dechex";$result;$1) End if $0:=$result

If the above code is saved as a project method named UTIL_php_DecToHex it could be used to convert an integer value to a hexadecimal value like so:

C_TEXT($hex) $hex:=UTIL_php_DecToHex(64784)

In the above example $hex would be equal to "FD10".
