Thanks for answering. Here it goes:

#!/usr/bin/env ruby

class OrangeTree

MSG_GROW = "Type \"year\" to grow your tree."
MSG_PICK = "Type a number to pick some more fruit. "
EXIT_TXT = "Something went wrong."

def initialize # we have one tree, does it need a name?
	@heightInches = 0 # at year zero
	@age = 0
	@fruit = 0 # inches, work out feet and inches later
	puts "Congratulations, you planted an orange tree. In a few years it 
will start bearing fruit. #{@age} " # Age only for debugging. Can take 
it out.	 	
	puts MSG_GROW
end

	def ageOneYear
	 	@heightInches = @heightInches +1
	 	puts 'Height: ' + @height.to_s
	@age += 1
		# @age = @age + 1
	 	puts "Got to ageOneYear. Age: #{@age}"
	 		case( @age )
				when (1..3) :  puts("Your #{@age} year old tree is too young to 
bear fruit yet. #{MSG_GROW}" )
				when (4..29) : puts(" Age: #{@age}. Place holder until get 1..3 working." )
			 	when (30) :    puts("Your tree was very fruitful, but it reached 
old age and died.")
				else puts( " Something went wrong. #{EXIT_TXT}" )
			end
	end # def ageOneYear
	
	def height
		# returns the height	  
	end
	
	def pick_an_orange
	 puts 'Got to pick_an_orange, but haven\'t defined yet'
	  # reduce this year count by one
	end
	
end # class OrangeTree

# here we go 
countLoop = 0
tree = OrangeTree.new # assume we need to initialize it. Does it need a name?

while countLoop < 100
	countLoop += 1
	puts "countLoop = #{countLoop}"  # debugging.
	if gets.to_s=='year' 
			puts 'In the gets.to_s if clause' # debugging. 
			tree.ageOneYear 		
	end
	
	gets case 
		when 'year' : tree.ageOneYear # , y as shortcut?
		when (1..100) : tree.pick_an_orange
		else puts('Don\'t be greedy, don\'t try to pick more than 100 oranges')
	end
	
end # while

TextMate response. I answered 'year' to each request for input:

Terminal response. All 'year' are my responses. I stopped after two 
none reponses.

 TextMate was close, but I expected values for @heightInches to 
increase with each iteration.
 
 I would like it to work in BBEdit, but realize BareBones support for 
this is weak. But at least Terminal should get it right. I own BBEdit, 
so am reluctant to buy TextMate, particularly since it has significant 
features I would like missing.
 
 Thanks for any help.
 
 I hope this isn't a double posting. My original was via Usenet, then I 
found the Google Groups and tried to post there, but I am not sure I am 
a member there. This version may be somewhat different as I had to 
recreate it after realizing Google Groups wasn't working for me.
