GetValue

Use this function to return a string that contains the contents of the DAL symbolic variable specified by the parameter. You can use this function when the name of the DAL variable is also stored in a variable, such as when a variable has to be addressed in another external script.

Syntax

GetValue (Symbol)

Parameter	Description
Symbol	Enter a string that specifies the name of a DAL symbolic variable. This can be from an expression or from another string variable.

Note

You will get a syntax error if you omit the Symbol parameter or if the DAL symbolic variable does not exist. It is wise to use this function with the Exists function.

Example

Here are some examples. Assume the...

String variable 'my_variable' contains: "Hello World"
Numeric variable '#_veh' contains: 20
String variables 'tbl_1', 'tbl_2', 'tbl_3', and 'tbl_4' respectively contain: 'Ford', 'Chev', 'Olds', and 'VW'.

In this example, the variable named contents is set to the string "Hello World":

variable_name = "my_variable"

contents = GetValue(variable_name)

This example stores the value, 20, in the field entitled 'total # of vehicles' in the current section:

SetFld ( GetValue("#_veh"), "total # of vehicles")

In this example, if #line is set to 3, the string 'Olds' is returned. If #line is set to 5, a 'blank' is returned.

If Exists("tbl_" & #line) Then

           Return ( GetVaule("tbl_" & #line) )

      Else

           Return (" ")

End
