The reason they didn't choose tcl had nothing to do with the language. > 2. An attempt was made to port each scripting engine to the VxWorks real-time operating system on a flight-like Power PC by embedding it into a payload flight software application. TCL was dropped from the study when it could not be successfully ported to VxWorks. JavaScript, Python and G-script were successfully ported and a series of tests with prototype flight software applications were run in order to rank them against the success criteria. https://www.scribd.com/document/407354589/Event-driven-James-Webb-Space-Telescope-operations-using-on-board-JavaScripts https://www.scribd.com/document/407354589/Event-driven-James...
