679	 Recent Improvements in MADCAP	 MADCAP is a programming language admitting subscripts superscripts and certain forms of displayed formulas. The basic implementation of this language was described in a previous paper MADCAP A scientific compiler for a displayed formula textbook language Comm. ACM Jan. - . This paper discusses recent improvements in the language in three areas complex display logical control and subprogramming. In the area of complex display the most prominent improvements are a notation for integration and for the binomial coefficients. In the area of logical control the chief new feature is a notation for variably nested looping. The discussion of subprogramming is focused on MADCAP s notation for and use of procedures.
