- Subject: Lua 5.0 using old Plua on PalmPilot
- From: Doug Rogers <rogers@...>

Lua and PalmPilot afficionados,
I have attached a simple set of table definitions to map the Lua 5.0 names
back to Lua 4.0 that is used by Plua on the PalmPilot. I then put the
following at the top of each of my Plua memos:
if string == nil then dofile "memo:lua5.lua" end
I find this to be useful - at least until the new PalmPilot Lua project is up
to speed.
Doug
