Strings and File I/O continuedContinuing on Today with my work on LabVIEW, I am slowing down the pace a little so that I can focus more on my classes and schoolwork than my research. However, I am going to attempt to work on research four hours a day on Tuesdays, Wednesdays and Thursdays. Today, I generated a subVI that concatenates three strings into a single string. The original pair of strings contains the sentence fragment "The measurement is", while the second one is a number, and the final is the units, called a "trailer". File I/OFile I/O stands for file input/output, and is the overall title for operations that pass data to and from files. Their several uses includes, opening and closing data files, reading data from and writing data to files, moving and renaming files and directories, and creating, modifying and reading configuration files. Of all it's functions, the palatte containing File I/O operators has four different levels: high-level, low-level, advanced and express. Rundown of file types:
General Process for a File I/O:
High-Level File I/O VI'sWhile most of the operators under the File I/O heading follow through only one step in the process, high-level ones wrap up the entire process into a single VI and execute it. There are not necessarily as efficient as the lower level vi's, however they simplify the programming and can be used to cut corners and make thing easier. There are several important VI's. They are:
