#128374 - well, you have to mix to get that

Besides, using malloc(), even if that would do it for you, in a '51 environment will give you enough overhead to solidify your resistance to C.

There are C operations, such as malloc(), that are singularily unsuitable for use with the '51 (remember C was developed for use on the UNIX behemots) and, while your compiler may support them, that does not oblige you to overburden the '51 by using them.

Jan, one of the advantages of an assembler background is that it allows you to think outside the (C) box.

Let us hope your next "I want to do it in C" is doable, this one is not. K&R did not have limited (data) memory on their computer.

(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
