read-from-string1.1

read-from-string string

Interprets the given string as if it had been typed in the Command Center, and reports the resulting value. The result may be a number, list, string, or boolean value, or the special value "nobody".

Useful in conjunction with the user-input primitive for converting the user's input into usable form.

show read-from-string "3" + read-from-string "5"
=> 8
show length read-from-string "[1 2 3]"
=> 3
crt read-from-string user-input "Make how many turtles?"
;; the number of turtles input by the user
;; are created

Note: This primitive is not compatible with NetLogo Web. If you wish to read user input with the same code and the same behavior in both NetLogo and NetLogo Web, see dialog:user-input.
