Hello friends I have problems with the selector of cases in type string.  I adquire data  rs232 next I form an array data to data al to read the port series then this array formed passes for array to spreadsheet string  which generates dates it for select the case string but drags dates damaged
then does not recognize the case.

Apparently, your raw string from rs232 does not get parsed correctly. Why do you process it so much? First you convert it to an array, then back to a string.

Please attach a small example with typical rs232 data contained in a diagram constant. Show us how you do all these conversions. What string do you get and what string do you want for the case structure?
