Re: How to detect NULL input?

Is there a way to determine if the return key is pressed while waiting
for input? I tried to do something like the code below in the line "if
(LLT(str1,'')) then" where I was comparing "str1" to ''. The program
didn't read the enter key...

      function evaluateinput(str1) result(string)
      implicit none
      character(12) str1
      character(12) string
      if (LLT(str1,'')) then
        string = 'less than'
      else if (LGT(str1,'')) then
        string = 'greater than'
      else
        string = 'equal'
      end if
      return
      end


Once again, replace

character(12) str1

by

character(*) str1

....and you should be OK.
