Siebel 2018: Declare Global Variable Statement

The Declare Global Variable statement declares a global variable. It does not return a value. You must declare a global variable in every module from which Siebel VB must access that variable. You declare a global variable in the general declarations section of the module.

Format

Usage

If you do not include the As clause, then you can add a type character as a suffix to the variableName argument. You can simultaneously use the two different type specification methods in a single Global statement, but you cannot use these methods simultaneously on the same variable.

Regardless of how you declare a global variable, you can choose to include or not include the type character when you reference the variable from another section of code. Siebel VB does not consider the type suffix as part of the variable name.

Formats That You Can Use to Specify the Type of a Global Variable

Visual Basic is a strongly typed language. You must assign a data type to a variable or Siebel VB assigns a type of variant.

Table 24 describes the data types you can use to specify the type of a global variable. Declaring a global variable is the same as declaring a variable, except where noted in the Format column in Table 24. The Reference column includes a link to the description for declaring a variable.

Table 24. Formats That You Can Use to Specify the Type of a Global Variable
Type	Format	Reference
Array	You use the following format to declare a global record: `Global` variable`([` subscriptRange`, ... ]) [As` typeName`]` where: subscriptRange uses the following format: `[`startSubscript `To]` endSubscript	Declaring an Array Variable
Number	Not applicable.	Declaring a Number Variable
Record	You use the following format to declare a global record: `Global` variableName `As` typeName You cannot use the Declare Global Variable statement to declare a dialog record.	Declaring a Record Variable
String	You use the following format to declare a global string: `Global` variableName `As String ` length* You use one of the following formats to declare a dynamic string: `Global` variableName$ `Global` variableName `As String`	Declaring a String Variable
Variant	You use one of the following formats to declare a global variant: `Global` variableName `Global`variableName `As Variant`	Declaring a Variant Variable

Example

The following example includes two subroutines that share the total and acctno variables, and the grecord record:

(general)(declarations)
Option Explicit
Type acctrecord
acctno As Integer
End Type

Global acctno as Integer
Global total as Integer
Global grecord as acctrecord
Declare Sub CreateFile

Sub CreateFile
   Dim x
   x = 1
   grecord.acctno = 2345
   Open "c:\temp001" For Output as #1
   Do While grecord.acctno <> 0
      grecord.acctno = 0
      If grecord.acctno <> 0 then
         Print #1, grecord.acctno
         x = x + 1
      End If
   Loop
   total = x-1
   Close #1
End Sub

Sub Button_Click
   Dim msgtext
   Dim newline as String
   newline = Chr$(10)
   Call CreateFile
   Open "c:\temp001" For Input as #1
   msgtext = "The new account numbers are: " & newline
   For x = 1 to total
      Input #1, grecord.acctno
      msgtext = msgtext & newline & grecord.acctno
   Next x
   Close #1
      Kill "c:\temp001"
End Sub
