A domain function for MAPLE

A collection of MAPLE V Release 2 routines are presented that implement a "domain" type function (similar to the depend function of REDUCE [1]) for MAPLE. This avoids the tedious requirement of always specifying the functional dependencies when using MAPLE. Further, an extension of dsolve is presented that exploits this domain function. The domain function is also exploited in the author's package to determine symmetries of differential equations [2]
