  • LWord (number) – 5

  • SInt (number) – 6

  • Int (number) – 7

  • DInt (number) – 8

  • LInt (number) – 9

  • USInt (number) – 10

  • UInt (number) – 11

  • UDInt (number) – 12

  • ULInt (number) – 13

  • Real (number) – 14

  • LReal (number) – 15

  • String (number) – 16

  • WString (number) – 17

  • Time (number) – 18

  • Date (number) – 19

  • DateAndTime (number) – 20

  • TimeOfDay (number) – 21

class TypeIds()

enum {number} with all specific type ids

Arguments
