Local Variable

Available Variable Types for Local Variable

The following variable types can be used as local variables in the same manner as global variables.

• Type I: Integer variable (range: - 2147483648 to + 2147483647)
• Type F: Floating-point variable of type real (-3.402823E + 38 to 3.402823E + 38)
• Type D: Double-precision variable of type real (- 1.79769313486231D + 308 to 1.79769313486231D + 308)

• Type S: String variable (maximum of 243 characters)

• Type V: Vector variable (X, Y, Z)
• Type P: Position variable (X, Y, Z, RX, RY, RZ, FIG)
• Type J: Joint variable (J1, J2, J3, J4, J5, J6) (6 axes) (J1, J2, J3, J4)(4 axes)
• Type T: Homogeneous transform variable (X, Y, Z, Ox, Oy, Oz, Ax, Ay, Az, FIG)
• Type IO: I/O variable

Declaring Local Variables

Local variables can be used after type declaration is executed using type declaration commands.

Type declaration can also be executed using the type declaration characters for numeric value type and character string type local variables.

There are two ways to declare local variables as shown below.

Type	Declaration example 1	Declaration example 2
Type I	Dim AAA As Integer	AAA%
Type F	Dim AAA As Single	AAA!
Type D	Dim AAA As Double	AAA#
Type S	Dim AAA As String	AAA$
Type V	Dim AAA As Vector	－
Type P	Dim AAA As Position	－
Type J	Dim AAA As Joint	－
Type T	Dim AAA As Trans	－
Type IO	Defio AAA	－

Defio is used for IO type only and Dim is used for other types of variables.
As Declaration example 2 shows, postposition is available for I, F, D, S type to declare.

    Dim Denso As Integer 'Declare integer variables Denso 
    Dim Robo As Integer 'Declare integer variables Robo 
    Dim AA As Double 'Declare double-precision variable AA
    DefIO Port = Byte, 104, &B00101011 
    'Declare the IO variable Port and use 8 bits (BYTE) 
    'starting from input port   104
    CC% = Denso*2 'Declare the integer variable CC and assign 
    'the calculation result of "Denso*2" to it
    DD$ = "Denso Robot" 'Declare the string variable DD and assign the 
    'string "Denso Robot" to it
    AA = F[5]/5 'Assign the result of the right side 
    'to the double-precision variable AA
    In Robo = Port 'Convert I/O data of Port into decimal and    
    'assign it to the integer variable Robo
