Library Only Mode

It is sometimes a burden to have complex languages such as GREG1 $\backslash$ in your HELP when you just want to use the library version of the language. SIC provides a way to load a language in ``Library Only'' mode. This means that the commands are accessible only through a US_EXEC like program and not through SIC monitor capabilities. This mode is useful for building another more elaborate language from one (or more) lower level languages (pay attention to possible recursive programming in doing so however). This mode is called by loading the corresponding language with a null help specification :  

           SIC_LOAD(LANG,' ',MCOM,VOCAB,VERSION)
