1. The GET$ function can be used in two ways; either to retrieve data from an existing file, or to run another program that generates a file from which GET$ retrieves data into a TeLiTab.
2. GET$() is an alternative for for GET$ as it returns ALL output in file FileName$ in the form of a single string. The result can be assigned to a string parameter which in its term can be used as data source Telitab$ for other functions such as interpolation or integration. GET$() can be used with programs using and producing Telitab data but also by those working with file IO in an arbitrary format. GET$ checks  checks the necessity of rerunning a program by comparing the current input with previous input. GET$() always reruns without comparing previous with new input. GET$() in combination with TEMPLATE$() and PUT$() is comparable with GET$ using an input template, viz. a structural recipe for the (single) input file. GET$() can create multiple input files each using their own template ( TEMPLATE$() ).
3. Please note that the Process$ can be the execution of a batch file that is carrying out several command line actions. Furthermore, this batch file itself can be generated knowledge based by means of a PUT$() combined with a TEMPLATE$() action. Using the report path where the batch file is saved in the Process$ (use SYSTEMVAR$() to request the path from Quaestor) the approach enables many programs and processes to be executed in a very flexible way. Look on the internet and documentation of the processes you want to execute about detailed possibilities.
4. Furthermore, please realise that you can use the @COPYFIRST attribute to make sure some required external files are copied to the working directory prior to running the program specified in the GET$. Furthermore, when you add the process itself to the @COPYFIRST Quaestor will remove any path information given in front of the process in the GET$ function.
