 Andy Wildenberg - displaying sets/curly braces in PG  5/6/2001; 9:36:24 PM (reads: 1944, responses: 3) How do I include curly braces in my PG problem's text? I can't use { because that's interpreted as something by LaTeX, and I can't use slash { because that confuses the heck out of the PG translator since it's also reserved. slash slash { doesn't work either. Heck, I can't even post the question in this forum without writing out the name of the slash symbol longhand?! I would hope that there was a macro defined for this, but unfortunately all the online docs are empty :-( Any idea when they're coming back? <| Post or View Comments |>

Or you can follow the links: write/modify problems -> PG advance reference ->PGbasicmacros-> display macros Some of the online docs are out of date (catching up will be among the first tasks when our interns start work this summer). The docs in the advanced section are actually taken from the current pod documentation in the code and are (usually) the most up to date and detailed. Hope this helps. Take care, Mike <| Post or View Comments |>

The organization needs workand there is also basic documentation working. As I said, it hasbecome a priority, but it may still take some time ...Thanks for your quick response! -- Andy>Thanks for your quick response! >-- AndyThe links you mention were really were pretty obsolete, so I've removed the links for the moment to avoid confusion. I'm hoping that the manpages sectionwill essentiall replace the functionality that these pages once provided.(They were written by Leeza Pachepsky, who worked for us more than 3 years ago!I don't think they have been updated since.)-- Mike <| Post or View Comments |>
