Batch Scenario Overview
To remove a global variable, simply select it on the table and select the Delete button. The variable is removed from the right pane of the dialog.
The Up and Down arrows (Figure 5.15) let you rearrange the order of variable values that you wish to change, before Net Protocol Suite runs a scenario. For most fields, the order does not matter, but for the fields that do change the format of events, this order becomes important. For example, suppose you want to change the value of the field Opcode in a SCSI command, and then change one of the other fields in that SCSI command. You will have to move the Opcode field to the top of the list, because when you set Opcode fields, the event fields will be changed automatically. Then you can change the value of another field. On the other hand, if you want to set the value of a field such as Originator S_ID, changing its value has no effect on the format of other fields in an event, so you don’t need to specify the order in which these fields are accessed.

Note: Replacing any value in a frame pattern or event may cause other fields values to reset. To avoid this, make sure you select the correct order of global variables.
For example, assume there is a batch scenario with one “Start Jammer” command and global variables as shown in Figure 5.16 and Figure 5.17.
