substr in c shell scripting

[sjh7899]

I am very new to unix scripting and I have some up against a problem and i cant find any documentation on it. I simply want to substr out part of a string and assign it to another var. Something like this....

set var = substr($another_var,1,3)

If anyone could help me out with this i would really appreciate it.
Steve.

another="some text"

var2=`echo $another | awk '{ print substr($0,1,3)} '`

echo var2

result:
som

Cheers.

Another solution using 'expr'
[tt]
set another_var="some text"
set var = `expr substr "$another_var" 1 3`
[/tt]

set another_var="some text"
set var = `echo $another_var | cut -c 1-3`

Thanks everyone! I actually ended up using the cut command. Thanks to all for your input.

Just thinking...
