CRBasic Example B-3. Variable Data Type Declarations
'This program example demonstrates various data type declarations. If not otherwise specified, data
'types default to floating point: As Float in Public or Dim declarations.
'Float Variable Examples
Public Z
Public X As Float
'Long Variable Example
Public CR300Time As Long
Public PosCounter As Long
Public PosNegCounter As Long
'Boolean Variable Examples
Public Switches(8) As Boolean
Public FLAGS(16) As Boolean
'String Variable Example
Public FirstName As String
BeginProg
'Program logic goes here
EndProg
B.2.2 Declaring Arrays
* 16 'allows a string up to 16 characters long
Multiple variables of the same root name may be declared. The resulting series
of like-named variables is called an array. An array is created by placing a
suffix of (X) on the variable name. X number of variables are created that
differ in name only by the incrementing number in the suffix. For example, the
four statements
Public TempC1
Public TempC2
Public TempC3
Public TempC4
can simply be condensed to
Public TempC(4).
This statement creates in memory the four variables TempC(1), TempC(2),
TempC(3), and TempC(4).
A string array called StringVar, with five elements in the array and each
element with a length of 36 characters, is declared as
Public StringVar(5)
This statement creates in memory the five variables StringVar(1),
StringVar(3), StringVar(4), and StringVar(5).
StringVar(2)
,
A variable array is useful in program operations that affect many variables in
the same way. CRBasic Example
