string manipulation

[Luinrandir Hernson]

OK.. thanks to all who helped me... i'm actually learning this thing... perl....

In BASIC there are commands for leftstring, midstring, and rightstring.
I am looking for the perl equiv for these.
maybe an example too??? not in butt tight code, but in line by line code so I can 
learn.
THEN I'll share and ask for the "tight" code.

Lets say i have a string 80 charecters long and i want to insert at string position 20 
for 10 charecters.
