In most every text-based programming language there are built-in functions to convert a character to its decimal ASCII code and a decimal ASCII code value to its associated character. In BASIC, for example, ASC(character) does the former and CHR$(code) does the latter. In LabView you have to implement these functions yourself from scratch with a CASE structure. If you want to do the whole 7-bit character set you need 128 cases. This is a waste of time! Since many instruments use single ASCII charcters as their commands why not include such functions in LabView?
