(SCL) The command language for the vme/b operating 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.
