How to limit a string?
Hi,
I have some data that I am reading from a text file, and some of the data is PowerCylinderTemperatureHistogram and some is PowerCylinderTemperatureHistogramBreakpoints. Now when my code is filtering through the text, it associates the PowerCylinderTemperatureHistogramBreakpoints with PowerCylinderTemperatureHistogram, how can I limit that text that is chooses to JUST PowerCylinderTemperatureHistogram and not the Breakpoints?
