printf() as first line and number formatting

EvanShultz

OK, here's a weird one for you. I want to print some information for the user into the Command window before I do anything else. So, I figured why not make a printf() statement the very first line of code? I suppose it should work - George does it on lines 25-35 of tekTechFileXML.il (from SourceLink). But for me, nothing is printed in the Command window. If I move the exact same statement as the first line of the procedure(), the text is printed to the Command window.

So what's my problem? Well, farther down in the procedure() a subroutine is called which uses axlEnterPath(). And the "Enter first point" prompt from axlEnterPath() comes BEFORE my printf() text, even though the printf() comes first in the code. My mind is boggled. I changed the prompt for axlEnterPath so I know it is this SKILL function that is creating the prompt which is jumping ahead of my printf() text.

Any ideas why this SKILL function can't wait it's turn? Or, better yet, how can I get the string in a printf() statement to show in the Command window if the printf() statement is the very first line of the SKILL routine?

 

 Secondly, I want to print out a table of information which may be integers or floating point numbers. How can I do this while keeping the table nicely lined up? Here is what I've found:

%-10n - displays both number types, but pads with zeros for floating point numbers

%-10g or %g - barfs on integers

%-10L or %L - displays both number types, no padding zeros for fp, but ignores [width] field (as per page 170 of sklangref.pdf)

So, what options do I have? I want similar to %-10n output, but without zero padding. %-10g would seem to be the right choice. I've used %g in other SKILL programs and it gracefully handled both integer and fp numbers - any ideas why it isn't with integers for me now?

     Hi Charlie,

    Hmm, axlMsgPut still doesn't print if it's the first line, but it does print before axlEnterPath (when printf doesn't). So I'm satisfied. So is axlMsgPut best suited for displaying in the Command window and printf is best used for anything else (external file, buffer, etc)? Thanks!

     

    For my second issue, %g doesn't work in the other code I was referring to - it barfs on integers there too. I don't know what I was thinking. So, how can I place either integers or fp numbers in a certain width of field without having zeros padded?
