;In my program code file: After beening assembled, there are many surprising errors. The detail error are shown as follow. mov r8, #3F7Bh; The error message is "error a6: SYNTAX ERROR" addc r9, #0Fh; The error message is "OPERAND TYPE MISMATCH" I have identified the codes of above instructions are right. Furtherly, these errors did not appear in every code file. I am stopped by the puzzle. My software condition: KEIL uVsion2 for C166 Processor: C167CR-LM
"which line that the keil reports error message is NOT the actual line where some errors happened." That is normal behaviour for any 'C' compiler with certain types of error such as missing semicolons or closing braces. "KEIL CAN NOT REPORT THE PRECSION LINE NUMBER OF HAVING ERROR IF YOU PROGRAM HAS MORE THAN 65536 LINES" I presume you mean 'if a single source file has more than 65536 lines'. I guess they (probably quite reasonably) thought nobody would do that.
