HDBCALC - HEX/DECIMAL/BINARY CALCULATOR
---------------------------------------
(C) Copyright 1988, Jim Lynch
Ver 1.00
USER MANUAL
-----------
INTRODUCTION
------------
HDBCALC is a 16 bit programmers calculator, distributed in its
non-memory resident form as Shareware, and may be freely copied
and distributed, unaltered, provided this document file accompanies
the program. If you find this calculator useful, a $10 registration
fee is required, for which you will receive the memory resident
version. Comments and suggestions are also welcome. Thank you very
much.
SYSTEM REQUIREMENTS
-------------------
HDBCALC requires DOS 2.xx (memory resident version requires DOS 3.xx).
Both versions will run on monochrome and color (CGA, EGA & VGA) video
adapters.
CALCULATOR DISPLAY
------------------
The main display uses hi-liting to indicate which numbers are
the result of the current operation (bright), and which are left
over from a previous operation (normal); therefore it is important
to adjust the brightness/contrast of your monitor so that bright
and normal can be distinguished.
Numbers can be entered into any field by using the function keys
to move the block cursor. Math and Logical operations are selected by
positioning the block over the desired operation and pressing ENTER.
The result of the operation will appear in Line C.
Single number operations (i.e., SHR) are performed on the number
in Line A.
To perform repeated operations, press the PageUp key to move the
result values (Line C) to Line A, and then repeat the desired
operation.
In the lower right hand corner, two status flags are shown. These
reflect the state of the CPU's status flags as set by the last
operation performed.
FUNCTION KEYS
-------------
Complete on-screen help is provided for function key operation,
and is not repeated here. One thing that may not be self-evident
is how to exit from the shareware notice or move from the help
window back to the calculator - press any key.
