  13. In article <BxwrJC.GME@cs.uiuc.edu>, ctaylor@cs.uiuc.edu (Conrad W Taylor) writes:

  20. I don't know why it would object to .TRUE. Like that, (CAPITALS, dots
  21. immediately adjoining the keyword (yes, I've known compilers to complain
  22. about . TRUE .)) it is standard Fortran. However,
  23.  
  24.         IF (CheckActivity(previous, ROWS, COLS) )  THEN
  25.  
  26. also works. Your variable being a logical, you can test on it immediately.
