noob question: why 3 different outputs

Hello, Can someone explain what is going on that causes these three very similar (to me!) inputs to have such dissimilar outputs? Thanks. Doug Edmunds ;-------code starts REBOL [Title: "block creation tests"] myfunc: func [ myfields ][ print "print block:" print myfields print "print foreach:" foreach myfield myfields [ print get myfield ] print "---" ] view layout [ myfield1: field "doug" myfield2: field "was" myfield3: field "here" mybutton1: button "button 1" [ myfields1: [myfield1/text myfield2/text myfield3/text] print "button1" myfunc [myfields1] ] mybutton2: button "button 2" [ m1a: myfield1/text m2a: myfield2/text m3a: myfield3/text myfields2: [m1a m2a m3a] print "button2" myfunc [myfields2] ] mybutton3: button "button 3" [ m1b: myfield1/text m2b: myfield2/text m3b: myfield3/text print "button3" myfunc [m1b m2b m3b] ] ]

The q should be Why 4 different outputs? I left this one out: mybutton4: button "button 4" [ m1c: myfield1/text m2c: myfield2/text m3c: myfield3/text myfields3: reduce [m1c m2c m3c] print "button4" myfunc [myfields3] ] DougEdmunds wrote:

Hi Doug ~ hmm, none of the gurus who have helped me out so often have replied yet, so I will take a stab: Probe and "type?" are your best friends here. Take a look at what you are passing to your function with probe myfields print type? myfields1 probe myfields1/1 print type? myfields1/1 etc. Do this for all 4 and you will see that what seems to be a subtle difference is a big one in Rebol (some learning curve for programmers coming from more "conventional" languages). Also, remember that everything inside a block is 'safe' from evaluation - unless you ask Rebol for it, as you are doing via "reduce" in example 4 HTH Kai

Hi Doug, I did not read your question closely, but it looks like more word/value confusion. Perhaps this tutorial will help: do http://anton.wildit.net.au/rebol/doc/rebol-values.r Regards, Anton. DougEdmunds wrote:
