Xbasic

TYPE ... END TYPE

Syntax

TYPE Xbasic_Structure_Name SubVariable1 as Type1 SubVariable2 as Type2 SubVariableN as TypeN END TYPE

Arguments

Xbasic_Structure_Name

The generic name of the variable type that you are creating.

SubVariable1 ... SubVariableN

The names of the components of the structure.

Type1 ... TypeN

The variable type of each component:

N

numeric

D

date

C

character

L

logical

P

pointer

T

time

B

blob

U

collection

A

any type

Integer

32 bit integer, equivalent to C long int

Short

16 bit integer, equivalent to C short int

Byte

8 bit integer, equivalent to C unsigned char

{YourType}

a user defined type created with a different TYPE ... END TYPE command.

Description

Defines an Xbasic structure.

Discussion

TYPE ... END TYPE defines an Xbasic structure, which allows you to quickly define dot variables with sub-variable names defined by the Xbasic_Structure_Name.

In many cases, using an Xbasic class will be preferable to using the TYPE command. See example below. See also DIM.

Examples

' Declaring Variables Using a Structure
' Define the structure.

type customer
    name as C
    company as C
    phone as C
    age as N
end type

dim cust as {customer}

? properties_enum(cust)
= NAME
COMPANY
PHONE
AGE

dim custs[10] as {customer}
? properties_enum(custs[1] )
= NAME
COMPANY
PHONE
AGE

' The Windows POINT structure would be represented by :
type point
    x as integer
    y as integer
end type

' a new type contain point types
type line
    x as {point}
    y as {point}
end type

Example: Using an Xbasic Class

define class myclass
    dim name as c 
    dim time_start as t
    dim duration as y
end class 

dim b as myclass
?b 
= name = ""
duration = 12:00:00 00 am
time_start = 00/00/0000 12:00:00 00 am
