Post by thread:[PICLIST] Array Location in Assembly for "C"

Greetings, How do I define the memory location of an array in HI-TECH C so that when I reference the array in assembly, I can appropriately use the _INDF and _FSR registers in assembly for array manipulation? In my particular example, I have identified arrays in C as follows: static bank1 unsigned char data1[59]; unsigned char data2[48]; Thanks Peter Schultz Minimed Inc. 12744 San Fernando Road, Sylmar, CA 91342 Phone: (818) 362-2358x3837 Pager: (818) 589-3148 E-mail: spam_OUTPeterSTakeThisOuTminimed.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
