I'm new to Ruby, having worked with Perl the past couple of years. I'm
having trouble calling a method to increment a counter, and I'm assuming
that the problem is with the scope of the variables?
I'm getting the following error message:
P:/PETERV2/scripts/vlog2.rb:25:in `test_meth1': undefined method `+' for
nil:NilClass (NoMethodError)
from P:/PETERV2/scripts/vlog2.rb:47
from P:/PETERV2/scripts/vlog2.rb:36:in `each'
from P:/PETERV2/scripts/vlog2.rb:36
from P:/PETERV2/scripts/vlog2.rb:7:in `open'
from P:/PETERV2/scripts/vlog2.rb:7
This is the method I'm trying to call:
def test_meth1
counter = counter + 1
return counter
end
This is the call:
case typrec # case statement
example.
when "TR001"
cntr = test_meth1
puts cntr # Here I want to print the counter value.
when "AB001"
ab001 += 1
when "AI001"
ai001 += 1
else
puts "Invalid message type"
end
I assume that there's a really simple mistake I'm making, so any help
would be greatly appreciated.
