if statment, based on retune value

im working on a project for the iphone to write a termainal based program
we have bsd subsystem installed so have access to most unix command

i have a executable called coordinates, which get the coordinates of the iphone

when this runs it returns to the terminal the text of "success" or the text of "failed"

i want to write a shell script that will run different code for each, somthing like

if (result of coordinates = "success") then
{chunk of code1}
{chunk of code2}

end if

anyone got any ideas that could help?

# 2  
if [ $return == Success ]
