I don't know about a code

Well I'm trying to make a house with a turtle in the big dig mod-pack and i realized i have no idea how to make it execute the code i already wrote again after an if statement.

I suggest going here and read some tutorials about basic computercraft. the wiki is also a great place to learn.
I'm not gonna explain basic lua and computercraft here because its written in about 200 tutorials over the internet already ;)/>

LUA reference manual: http://www.lua.org/manual/5.1/
the wiki: http://computercraft.info/wiki/Main_Page
programs section, how i learned: http://www.computercraft.info/forums2/index.php?/forum/12-programs/

thanks for the help i just did something else anyway and i couldn't find it on the internet or the wiki
