#48620 #String Gadgets Message #48640

Mike, The routine you want is ActivateGadget(). Here's how… Success = ActivateGadget(Gadget, Window, Request) D0 A0 A1 A2 BOOL Success struct Gadget *Gadget struct Window *Window struct Request *Request The Window must point to a Window with the Gadget in it. If the Gadget is in a Requester, the Requester…

#t-card serial Message #48622

Todd, that was a "printer driver". John was wanting a different beast. The Amiga is blessed with documentation that is a little fuzzy around the edges, and often things that go by the same name are actually far different. Some of the words with more than one meaning are "hunk",…

There is a sample (skeleton) device driver in the RKM, though I recently found out that the Addison Wesley versions of these books are missing some appendices. You may need to look in a 1.2 version from CBM. Someone also posted a RAMdisk driver to Usenet a while back, which…

#48278 #kprintf() Message #48302
From: Larry Phillips/ICUG Forum unknown · Programming January 12, 1987 12:54 AM
Try that OMD on "amiga.lib" for some very interesting routine names. I am looking at it with renewed interest ever since a friend of mine pointed out that it has its own printf function.

OOPS! That last line (jsr _LVOOpenLibrary(A6) has an extra space in it… the correct one is without the space. One more thing I forgot to mention… if I define a macro with more than one parameter, then try to pass them, I get an error on both substitutions. By trial…

kprintf() is documented in the RKM (1.1) in appendix F oops… make that KPutFmt (is that the same thing? Am I off base? Does anyone care? Who am I) Anyway, there are a few goodies there. Have a look.

I see the problem, but would probably prefer that an assembler handle these references between sections. From my personal point of view, the stuff I write with references outside the current section can be full addressing mode, and if I am really trying to shave cycles on a particular program,…

I haven't been able to locate anything specific, despite extensive searches of the autodocs and readme files. Never thought that maybe it would look for a specific file. Will dig out the old debugger and have a scan through the code for any likely looking names.

That's not just for copy protection, that's a widely known and practiced method for calling a routine withoiut having to set up the accumulator first.

John, It really depends on what marketplace you're looking at. Most commercial software seems to be Intuition based (at least most that is good). Here in the Data Libraries you will find more CLI stuff, probably due to the abundance of people writing code that use and are used to…
From: Larry Phillips/ICUG The Amiga Forum · Programming January 2, 1987 3:44 PM
John, I do like your analogy to a ches program. Since a compiler must accept your code without any way of knowing what you intend with your instructions, it must, out of necessity, generate more generalized output than what a good assembly programmer would write. Aztec does an awful lot…

From: Larry Phillips/ICUG The Amiga Forum · Hardware January 2, 1987 3:37 PM
Khalid, The first signs of power supply problems due to overloading usually come in one of two ways, depending upon the supply. 1. Complete shutdown of the supply, sometimes requiring you to switch off/on, sometimes resetting itself. 2. Erratic errors. In the first case, the supply detects an overcurrent condition…

Mike, While I can see your point about looking at it from an "end user" point of view, I still maintain that it is a 16/32 bit processor, and should be called as such. My reasoning is that there is a considerable difference in speed between the 16/32 and 32…
