Verify if INT, STR, REAL or whatever

I need to find out what kind of values some symbols are having.

There fore I know I can do the opposite. I need to verify if the symbol is something that I need to process.

Example

(setq example "Test")
(type Test)
STR

But what I would need to verify is something like this

(if
(= Test STR) ;this test is not working and this is the main question, hhow to verify this
("do this")
)

Of course this is not working and that is the reason I am asking. I need for different kind of symbols like I wrote before.

Thanks in advance

Sergio

I figured it out myself already. The answer is

(= Test 'STR)

Thanks anyhow

(if (= (type example) 'STR) 
  (do this)
  (otherqise do this))

Hello

Sorry for my noobish question:

What does the apostrophe stand for?

What does the apostrophe stand for?

Represents a Symbol, Read THIS

What does the apostrophe stand for?

Please refer to my tutorial: The Apostrophe and the Quote Function

The apostrophe ensures that the quoted characters are not evaluated and therefore passed to the type function as a symbol; however, as per my tutorial, note that the apostrophe/single-quote is used to declare any AutoLISP data as a literal, and is not limited to symbols.
