I have the following script in tcsh:

#!/usr/bin/tcsh -f

set groups = (one two three four)

foreach group ($groups)
    set go = "go_$group"
    eval "set val = $go"
    if ( $?val ) then
        echo "val is: $$val"
    endif
end

the output I’m getting is not the output I want. I’m getting:

val is: 7553go_one

val is: 7553go_two

val is: 7553go_three

val is: 7553go_four

I understand that 7553 is the pid…
How can I get the value of each variable go_one, go_two…?

Thanks!
