INTRODUCTION
The BASIC Stamp I and BASIC Stamp II have many differences in both
hardware and software. While it is trivial to recognize the differences
in the Stamp hardware, the modifications to the PBASIC command
structure are intricate and not always obvious. This appendix describes
the Stamp I and Stamp II PBASIC differences in a detailed manner to
aid in the conversion of programs between the two modules. This
document may also serve to give a better understanding of how cer-
tain features of the two versions can be helpful in problem solving.
TYPOGRAPHICAL CONVENTIONS
This Appendix will use a number of symbols to deliver the needed infor-
mation in a clear and concise manner. Unless otherwise noted the follow-
ing symbols will have consistent meanings throughout this document.
TOPIC HEADING
Each discussion of a topic or PBASIC command will begin with a topic
heading such as the one above.
MODULE HEADING
When separate discussion of a Stamp I or Stamp II module is neces-
sary it will begin with a module heading such as this one.

•
Inside the module section bulleted items will precede information on
the properties of various arguments for the indicated command.
CONVERSION:
When conversion between the two versions of PBASIC are necessary,
each set of steps will begin under the conversion heading as shown
above. This header will always begin with the word “Conversion”
and will indicate in which direction the conversion is taking place; i.e.
from BS1 to BS2 or from BS2 to BS1.
