Return the value of the variable defined by a string.
Eval ( string )
| string | string representing name of the variable. |
| Success: | the value of the variable. |
| Failure: | "" (empty string) and sets the @error flag to non-zero. |
If there is a need to use Eval() to read a variable, then in most situations Assign() should be used to create/write to the variable and IsDeclared() should be used to check that the variable exists.
#include <MsgBoxConstants.au3>

Assign("sString", "This is a string which is declared using the function Assign")

Local $sEvalString = Eval("sString")
; Display the value of $sEvalString. This should be the same value as $sString.
MsgBox($MB_SYSTEMMODAL, "", $sEvalString)
