In article <2120@sfsup.UUCP> shap@sfsup.UUCP (J.S.Shapiro) writes: Now that we have different screen sizes, it no longer suffices to hardwire things like the screen width. A DA is not really allowed to call InitGraf. What can I do (assembler is ok) to find out the values of the screenBits rect? DA's (and any non-'CODE' code, I think) are not allowed to access Quickdraw's global variables. (thePort etc, or qd.* if you are using MPW or Aztec C) (I didn't know Aztec used 'qd.' like MPW. Is this new?) If you consider multiple screen environments, there are two possible things you want. a) just "this" screen's rectangle b) the bounding rectangle for all screens. You can use 'GetWMGrPort(&grafptrVar);' which gives you grafptrVar->portRect, which is a Rect that encloses the entire multi-screen display space. And I'm not sure, but I *think* that grafptrVar->portBits.bounds is be the rectangle for just the "this" screen. This may be a MANX bug. Nope, it's the way DAs work.
