Re: cl.apl

    Hi Bill,
      
      as to my previous email, I have checked the EACH operator again
      and it seems like
      my previous suspicion regarding the EACH macros was wrong.
      
      I have created an automated testcase (see attachment) that
      compares the EACH results for both 
      primitive dyadic functions (which use the built-in non-macro
      variant of EACH)
      and for defined functions (which uses one of the EACH macros that
      I mentioned.
    
    You can run the testcase it with:
    
    apl -T Macros.tc
    
    Every run uses different test data and it shows no differences
    between the two variants. That doesn't fully prove that
    there are no faults related to EACH, but if there are any then they
    seem to exist in
    both the build-in EACH and in the macro based EACH.
    
    Regarding your initial problem, I share your view that the two
    expressions that you mentioned
    should be the same, but I can't quite see where the problem is. If
    one of the expressions
    does not execute (and you can't see know why) then you may want to
    try ]log 25 and ]log 26 to
    get more details.
    
    Happy Xmas to you and your family,
    Jürgen
