I want to write multiple if statements in assign.  The contents I want to write are as follows.

Returns true if x=1.  In the case of false, judge whether x=2 is true, and if true, true.  Otherwise, I want to write a process that returns false in one sentence.

It may not be written correctly because you are not familiar with the program.  However, the image is as follows.

if x=1 true

else  if x=2  true 

else exit.

Someone tell me.
