I added the following text to explain the notation used in procedure signatures: Parameters given in square brackets are optional. Unless otherwise noted in the text describing the procedure, any number of these optional arguments may be supplied, from zero to the full list. When a procedure returns multiple values, this is shown by listing the return values in square brackets, as well. So, for example, the procedure with signature halts? f [x init-store] -> [boolean integer] would take one, two or three input parameters, and returns two values. Marc F will find this an inadequate stopgap measure, but I just cannot go through four large documents of text, two of them larded up w/HTML markup, and change every occurrence over to some alternate notation at this late date. It seems readable enough to my eye... -Olin
