Hello PICLIST all, i am new to the list and to C programming language. In my test about the Optama C-compiler DEMO i came across a couple of bytes within the OPSXPICDEM.EXE looking like: ff 52 14 3d c8 00 00 00 or in english: call [edx+14] ; ? cmp eax,000000c8 ; 200 ?? jle 004a753d ; !? Since i am not familiar with assembly language - i programmed all my PIC project with Picstart Plus until yet - i cannot understand what the meaning of this lines might be. Is it eventually for 200 users max or something. Could any list member please explain for me. Thanx. Brain Lite ps. I also thaught about asking www.kanda.com , but i am afraid they probably wont tell me. -- http://www.piclist.com hint: The PICList is archived three different ways.
