One of the enhancements since 8.2 is that the user can edit the variable value in execution dialog. This will enable user to
set context and build and or change test data during execution. You have to
remember that changing this value won’t change the default value of the
variable, it is temporarily stored in memory till certify is rebooted.
Example:
If text Variable V1 has default value "abc" and user
wants to change the value temporarily, now they can do it through the
execution dialog.
