exec files, inclUding parameterization (with defaults), prorrpting for input

aroong others. These facilities should allol.ll you to create lOOdular.. flexible
exec files which are bOth pOlJlerful and easy to maintain.

generation of IIJorKShop conmands. The basic operation of the exec preprocessor
is as follol.lls. The preprocessor is invoked when the workShop shell recognizes a
cornnand to run an exec file. The preprocessor then reads and processes its input
