### 5/5 — Me

*2022-02-12*

I am not sure whom y’all are, but I feel I can trust you. Trust is something I don’t have much of.
I am not technically able to do much, and often wish I had never did this. Searched for 
my late fathers war records.  I suppose I have learned a little. My late father wrote a poem while he was in a foxhole in ww11, maybe I’ll share with you guys  
soon.

I use this to test my programs when I think of a solution when I'm out partying it is a nice noble learning environment

### 5/5 — 不错的应用

*2013-10-02*

界面并不华丽，但很实用化，功能也丰富。美中不足的是：本版更新前行号易发生错位，光标对不准，更新后似乎解决了，但想不到的是，竟然无法显示输入代码了。希望尽快修复。

### 5/5 — Realy good and honest

*2013-03-01*

I tried all the Lua Programming to run samples programs of the book Programming in Lua (First Edition) and this was the only one that run all of them. It also let me try and test first it's characteristics. I found it the  best way to learn and practice Lua Programming. The price is fair and I'm happy with this product.
