Hi all. Anyone know why some 'retlw 0' might appear after linking in mplabx? I normally use gpasm, but wanted to see if mpasm would generate the same code. I was surprised that two of the retlw's appeared at the start of the hex file, and probably others elsewhere, as the mpasm=20 generated code is 5 or 6 instructions larger. Also, I can't seem to control the order of linking from the IDE, though there was a reference this would be implemented by version 1.10 John --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
