An Alternate Index for the HP48 Owner's Manuals - 8/26/92 This index was compiled by scanning through the two-volume HP48SX Owner's Manual, extracting key subjects and assembling them in alphabetical order. The version of the manual used was part number 00048-90001, dated 1/90. Several categories of subjects were referenced multiple times in order to allow indexing of all subject key words. As a result, subheadings such as Commands, Functions, Keys, Menus, Objects, Operations, Rules Transfor- mations and Units contain their own subindexes. Although they contain no cross-referencing, subindexes Examples and Illustrations were included to make the index more comprehensive. In order to maintain consistency, special HP48 characters were referenced using their I/O Character Trans- lation form as described in the table on page 627 (of Volume II). The only exceptions are up-arrow, down-arrow, left-arrow, right-arrow and newline keys which have no character translation. These were represented by the symbols "\^", " \v", "\<", " \>" and "\<-'" respectively. There are undoubtedly some errors and omissions as this project was undertaken by hand. However, it is hoped that this index will be useful for finding entries in the HP48 manuals which are not currently covered by its original index at the end of volume II.
