This is probably the most complete and useful shell available for the 86. It has many useful features, including almost all of the features that we loved so much in previous shells, and some new ones as well. It also uses the functionalities of “Ztools” (a project that Will White was also involved in) that allows BASIC programmers to have access to various ASM capabilities. I am pretty sure that there are even more functionalities on the way in future versions. My only complaint about this program is that the included periodic table is a little bit inconvenient and lacking in information, but could easily be adjusted to contain more information about the elements and, with a reworking, could become much more convenient. Overall, I'd give this a 9.9 with the .1 off for the periodic table.
