Applescript if statement : greater than and lower than

Can I run an script if a variable is between 4 and 6 characters only ?

e.g

``````set serialNumber to ""
set theLength to (get length of (serialNumber as text))
if theLength is equal to 1 then
set serialNumber to "No Serial"
else if theLength > 4 and < 6 then
##do this
else if theLength is greater than 6 then
## do nothing
end if
``````

This is obviously not working : `else if theLength > 4 and < 6 then`

Change:

``````else if theLength > 4 and < 6 then
``````

To:

``````else if theLength > 4 and theLength < 6 then
``````

Or, since you asked "Can I run a script if a variable is between 4 and 6 characters only?", which is equal to `5`, you can also use:

``````else if theLength = 5 then
``````

In place of:

``````else if theLength > 4 and theLength < 6 then
``````

However, if testing between two numbers that are (one or) more then one, just use the variable twice in the test as shown above.

• For completeness—and given that "between" can be inclusive—it's worth including less than or equal to (`<=` or `≤`); greater than or equal to (`>=` or `≥`); and not equal to (`/=` or `≠`). For example, `if theLength ≥ 4 and theLength ≤ 6 then...` catches `theLength` when its value is 4, 5 or 6; and if we know that `theLength` only evaluates to integers between 1 and 6 inclusive, this conditional is equivalent to the last: `if theLength ≠ 1 and theLength ≠ 2 and theLength ≠ 3`. – CJK Mar 13 '18 at 0:36
• @CJK, IMO It's not totally clear what the OP is actually looking for and why I left it as is, however you made some good points and feel free to edit them into the answer if your wish. – user3439894 Mar 13 '18 at 0:43
• Although the question is somewhat vague, I think your answer is just fine as it is. I think my additions serve better as a comment, as it's more of an aside, and not a correction or improvement, per se. – CJK Mar 13 '18 at 0:47
• Thank you that actually perfect, @user3439894 you right I was wrong in my question "< 6 then" (because I'm not sure of the Length yet, I have to check at the office) but anyway that perfect, exactly what I needed, thank you again. – Kevin Mar 13 '18 at 10:08
