(SCL) The COMmand language for the VME/Boperating system on the ICL2900. SCL was {block structured} and supported strings, lists of strings ("superstrings"), integer, Boolean, and array types. You could trigger a block whenever a condition on a variable value occured. It supported macros and default arguments. COMmands were treated like procedure calls.
