+===== Details =====
+''Ladybug'' is a more user-friendly, if less versatile, "HP16C programmer's calculator" module than the fully-featured HP16 module by Angel Martin. Both have their uses, but for a simple calculator for bit-banging while writing 6502 assembly code Ladybug does everything, with a less convoluted User Interface.
+Although I also have a DM16L, the Swiss Micros modern clone of the original HP16C, I am finding that having Ladybug on the DM41X allows me to quickly switch between "normal" floating point calculations and integer "programming" calculations, and have access to the best of both worlds.
+The DM16L/HP16C has very limited (basically unusable) floating point support.
+The Ladybug module is more intuitive and usable than the Angel Martin HP16 emulator module and having Ladybug for INTEGER and the rest of the DM41X/HP41CX functionality for other tasks makes the DM41X my go-to calculator. The DM16L //is// fantastic as a single-minded programmer's calculator, and is used extensively when I'm engrossed in writing assembly code, but the DM41X is much more versatile and is carried with me at all times when I'm away from the workbench.
+==== Launching ====
+  * modules needed:
+    * Ladybug
+    * Boost
+    * OS/4
+To switch to "Ladybug Integer" mode : <key>XEQ</key><key>ALPHA</key>''INTEGER''<key>ALPHA</key>
+To leave (and return to normal mode) : <key>XEQ</key><key>ALPHA</key>''EXITAPP''<key>ALPHA</key>
+Using the DM41X ''CST'' menu simplifies this, set 2 Custom menu entries for ''INTEGER'' and ''EXITAPP''
