Re: Of course there's a right answer!
Anyone who knows about keypunches KNOWS that yes there is a TAB key on an 029, and it is called the SKIP key. You set the columns you want to skip to on the drum card as god intended (you did take that class didn't you). Thankfully you could select on an 029 which settings you could use (PROG 1 and PROG 2) so the first was Fortran, the second was your Assembler (which had different tabs fields than the Fortran program did. When you used assembler, the skip positions were columns 10, 19, 37 as the proper gods determined. This allowed for 8 character labels.
Of course when you went to terminals (an ASR33 for sure), the software set things to have a tab every 8th column, so you used to after you typed your statement number in Fortran. Then tabs were ALWAYS set to 8 characters, and if you have a reasonable editor, it put them in for you even if you pounded on the space bar.
Of course when I was in typing class, the standard indent for paragraphs was 5 spaces, but that was a LONG time ago. Now it is 1/2 inch, which is the same thing on 10 cpi fix spaced fonts.
