Okay, I've been working on 1-13.

Once I broke it down into tasks, perhaps it isn't that difficult.

I have, perhaps, broken it down further than I needed to, but doing so helped me wrap my mind around the process I want the computer to do.

Now what I have is a program that runs, accepts input, and then exits, without printing my bars, and without any clues to what's going wrong.

I have a function that prints the bars, and it works, as long as I hardcode input into it.

So I built a "Project" in Xcode, hoping to use the debugger to run the program and find the problems.

I am now researching how to use the debugger; I don't understand what it's telling me. I don't know what the registers are, I don't know how to track my variables while I type input into the running program, it's like sitting in a big, powerful diesel locomotive, and not knowing where the start button is. You know you're surrounded with options, but none of them are turned on.

So if any of you have suggestions about a tutorial or ultra-basic instructions for using the Debugger in Xcode, I would be very interested in reading it.

Thank you, yet again. Smilie

Text::PDF::TTFont0(3pm) 				User Contributed Perl Documentation				   Text::PDF::TTFont0(3pm)

NAME
Text::PDF::TTFont0 - Inherits from PDF::Dict and represents a TrueType Type 0 font within a PDF file. DESCRIPTION
A font consists of two primary parts in a PDF file: the header and the font descriptor. Whilst two fonts may share font descriptors, they will have their own header dictionaries including encoding and widhth information. INSTANCE VARIABLES
There are no instance variables beyond the variables which directly correspond to entries in the appropriate PDF dictionaries. METHODS
Text::PDF::TTFont->new($parent, $fontfname. $pdfname) Creates a new font resource for the given fontfile. This includes the font descriptor and the font stream. The $pdfname is the name by which this font resource will be known throughout a particular PDF file. All font resources are full PDF objects. out_text($text) Returns the string to be put into a content stream for text to be output in this font. The text is assumed to be UTF8 encoded and the return string is a glyph sequence for the text. If subsetting is enabled, then all the glyphs returned are also marked for output. out_glyphs(@n) Marks the glyphs as being needed in the output font when subsetting. Returns a string to render the glyphs as specified. width($text) Returns the width of the string, assuming it to be UTF8 encoded. outobjdeep($fh, $pdf, %opts) Handles the creation of the font stream including subsetting at this point. So if you get this far, that's it for subsetting. ship_out($pdf) Ship this font out to the given $pdf file context empty Empty the font of as much as possible in order to save memory perl v5.8.8 2006-09-09 Text::PDF::TTFont0(3pm)
