5.11.2. Organization and Principles of Operation: SADIE is
organized as a tree of menus to provide its diagnostic func-
tions. Menu items are either submenu names (lower branches
of the tree) or functions (the end of the branch) of SADIE.
The tree is traversed by entering the choice required to
perform a function or to move to another menu on the path to
a function. Choices are entered on the console. Choices
are interpreted when the line on which they are entered is
terminated by a <CR>. In addition, the START and RESET but-
tons can be used to interact with SADIE.
The characters identifying menu choices are letters, in-
tegers, <CR> (carriage return), and A Ci on some terminals).
Entry of A causes a return to the menu from which the
present menu was selected or to the master (COMMAND LEVEL)
menu. A <CR> is used when there is only one choice or when
there is a default choice, as in verifying that a prior
choice is correct. Integers are used to identify tests,
test lists, or lines in a test list, or for entry of numeri-
cal constants. Numerical constants entered are interpreted
in decimal base unless the prompt indicates that the default
base is hexadecimal or octal. The default base can be over-
ridden by prepending 0 (zero) and a letter, d for decimal, 0
for octal, or x for hexadecimal for a specific number base.
Letters are used for all other choices. When a letter is
used, it is usually the initial letter of a capitalized key-
word in the item description .. Either upper or lowercase
letters can be used.
A sequence of menus can be traversed by entering appropriate
choices on a single line. Entries must be separated by one
or more spaces. The terminating <CR> is treated as a menu
choice if it is preceded by a space.
When a menu is too large to fit onto the CRT screen, entry
of + will get the next screen, and - will get the previous
screen.
SADIE maintains in memory both the current single test and
current test list. Initially the current single test and
the current test list only contain an EOL.
5.12fi SADIE Tape Organization
The SADIE tape contains the following data sets:
1. The bootstrap loader functions as a tape loading super-
visor that loads the SADIE machine code.
2. The SADIE machine code provides I/O support for tests.
When invoked, it loads the library and test list cata-
