[plt-scheme] DrScheme Interactions window

I have tested the GUI, it came up with the window (I had modified it so that
it had two text fields). When I entered the verb in however, it gave me an
error because it recognized the information in the text field as a string.
My verbs that I have defined as one-word variables that include a verb
structure with all the conjugations are not strings. They follow this
pattern

(define ser (make-verb "ser" "to be" "soy" "eres" "es" "somos" "sois"
"son"))

I tried changing it like so:

(define "ser" (make-verb "ser" "to be" "soy" "eres" "es" "somos" "sois"
"son"))

but it gave me an error saying that it expected a definition name or a
primitive operator after define but found a string. I know about the
functions number->string and string->number. Is there anything like that for
strings not made up of numbers?
