I'm not sure to know the question.
If you would like to write a value of initializing string in the cell control(in the execution is possible to chenge the initial value) I suppose you can try with a local variable .see the example code

Your question is not clear. What do you mean by cell, and is your control in a SubVI?
If you want to change an element in an array, use Replace Array Subset function from the Array palette, or to set one element in a string use Replace Substring fuction from the string palette.

Your question is very unclear. If you could give more details about what you are trying to do you will be likely to receive more useful information. Are you talking about setting a default value for a control? If so, just use the Make Current Values Default under the Operate menu.
