Till Launcher executes Till programs, shows the results and optionally can create an executable version of the program or designate the program as a global module. Till Launcher is the designated application for opening Till programs (files with extension “.till”). In case the default opener was changed, right-click on a Till file, start the “Open With” process, and choose Till Launcher (found also in the installation directory).

Here is an image of Till Launcher that runs project “linked-list.till” (found in the reference):

Till Launcher contains two boxes: code box and run box. When running a Till program, Till Launcher executes the program and shows the symbolized code in the code box. Then it starts the run box and waits for user interaction. Usually, the code does not need much time to run, so the results are printed in the run box. But when there is an interactivity, for ex. when using input fields, the run box will wait for the user to enter text. Eventually, if there is no endless loop in the code, the program will finish its running, and the results will be shown in the run box. In cases of error, Till Runtime error message will be shown in the run box.

CODE BOX BUTTONS

code source	The source of the code that will be loaded for running. It is a toggle button. If ON, the source will be the code in code box, else it will be the code of the Till file itself, thus enabling to edit the code in external editor
copy	Copy the text of code box
paste	Replace the text in the code box with the clipboard text
save	Save the text of code box to the Till file
rebuild	Rebuild the code of code box
run	Run the code of code box
