 		 #128331 - (SDCC): How to point to end of used memory?
An another question from the naive C-novice: I'd like to use the rest of unused XRAM as a "heap".

How can I set up a pointer to point to the end of used memory?

(I know, I know, I should not assume anything on hardware in HLL...)

(SDCC): How to point to end of used memory?            01/01/70 00:00      
   Make a dummy variable ???            01/01/70 00:00      
      A Better Idea            01/01/70 00:00      
         Good Point            01/01/70 00:00      
            A good point indeed...            01/01/70 00:00      
   SDCC options            01/01/70 00:00      
      this is still my fixation to asm....            01/01/70 00:00      
         Try this snippet?            01/01/70 00:00      
            Thanks!            01/01/70 00:00      
            Another bad idea?            01/01/70 00:00      
               it seems that this is hardwired in SDCC...            01/01/70 00:00      
                  More guessing            01/01/70 00:00      
               like that snippet?            01/01/70 00:00      
                  Yes!            01/01/70 00:00      
                  nice...            01/01/70 00:00      
   you do not want a 'heap' in '51 C, however            01/01/70 00:00      
      passing a #define to assembler within SDCC            01/01/70 00:00      
         NO, no, no            01/01/70 00:00      
            inline assembly versus separate assembly file            01/01/70 00:00      
               separate file is nicer            01/01/70 00:00      
                  good place to start, bad place to stay            01/01/70 00:00      
               that's the crux            01/01/70 00:00      
      Build-time scripts            01/01/70 00:00      
   the question of matter            01/01/70 00:00      
      have as much memory as possible            01/01/70 00:00      
         be sure or not to be?            01/01/70 00:00      
            easy            01/01/70 00:00      
               I'd disagree on this one...            01/01/70 00:00      
         well, you have to mix to get that            01/01/70 00:00      
            Did I miss something?            01/01/70 00:00      
               I thought I posted this            01/01/70 00:00      
                  Thanks            01/01/70 00:00      
            Do you think I would ask answerable questions? :-)            01/01/70 00:00      
               The Right Group?            01/01/70 00:00      
         Know no nice solution            01/01/70 00:00      
            thanks            01/01/70 00:00      
   Maybe compiler/linker settins help?            01/01/70 00:00
