LYNX Programming

The MicroLYNX uses the LYNX programming languange. This language is an
easy to use, BASIC-like language that follows standard programming conven-
tions. It features a powerful instruction set that allows the user to control a
broad spectrum of automated processes.

There are several recommendations for program entry that
optimize the user's ability to edit and debug LYNX programs:

1] The LYNX Variables, Instructions and Flags are not case
sensitive.
2] A space is required after each command, except in the case
where a variable or flag is being set to some value or state. In
this case no space is required between the command and the
"equal" (=) sign or math function.
3] A comma is required as a delimiter between data fields or
parameters where more than one data field or parameter is
contained in the command. No space is required between
delimiters and parameters.
4] The apostrophe ( ' ) is used as a comment character. Any
text on the same line after the apostrophe will be ignored by
the MicroLYNX.
5] Party mode device names defined by the DN instruction
ARE case sensitive.
1] The first and last instruction of every
program is the PGM instruction, which
toggles the MicroLYNX in and out of
program mode.
2] Subroutines invoked by a "CALL"
must have a return "RET" instruction on
the last line of the subroutine.
1] Always use the LYNX Terminal text
editor window or other ASCII text editor for program
development. While programs may be entered directly into
the MicroLYNX via a terminal, the entire program has to be
re-entered to edit or debug.

Using all UPPERCASE characters
for commands and lowercase
characters for comments make
for easier program editing
and debugging!
