Entering a File Name into a String Variable
The Professional license provides an option to fill a string variable with the name of file that is located using a standard Open File dialog. To use this option, select a string Input variable, as shown in the dialog below. Note that string variables end with the $ character. If the Use string list check box is not selected, the Browse for filename check box will appear. Place a check in this control.
Clicking in the input field for the string variable when the Diagram window is in Application mode will bring up an Open File dialog. The selected file name will be entered in the input field for the string variable. The string variable cannot be edited as clicking in the input field will again bring up the Open File dialog.
