Communicating with EFS

[z11]

With DDEOutput, EFS can "put" data into Excel. Is there anyway EFS can read data from Excel or some manual input to change a global variable's value from Outside of EFS other than via file I/O?

For example, is there a way to define a Button which accepts a user input and then assign the value of that input to a global variable of a running EFS? Thanks.

Hello z11,

To the best of my knowledge, file I/O is the only way to accomplish your task. EFS does not have the ability to read excel data. You could use a button on the chart that calls the askForInput() function, which opens a shortcut window to the Edit Studies parameters. However, making changes to the parameters with this method forces a reload of the formula in the same manner as Edit Studies.
