I have a bash script that calls an expect script like so 

```
$SCRIPTS_DIRECTORY/my_expect_script.sh $my_bash_array

```

I can pass a variable over, it seems, and use it. 
For this example the variable seems to be in `[lindex $argv 0]`.

From bash, it will be a bunch of values, e.g. `1 2 3 4 5`.

I am trying to figure out how to use expect to grab this variable, save it to an array then loop through the array to spit out multiple commands one at a time. 

So my output should be something like 

```
send command 1 \r
send command 2 \r

```

etc., until it reaches the end of the array. 

I thought in expect I would assign it like

```
array set myArray [lindex $argv 0]

```

but it looks like I am wrong.

Would anyone have any good places I can look that might explain going from bash to expect better, or know how to do this? I assume its relatively simple, but expect is very iffy with me in some aspects.
