I am thoroughly puzzled about this, any suggestions source starting line 152

There is a knowledgebase article that addresses this problem: http://www.keil.com/support/docs/2467.htm In a nutshell, you can create a project with 2 targets: 1 for debugging and 1 for production. (I prefer to debug using the production code.) In the Debugging target, set the optimizer level to 3. That causes the compiler and linker to perform no optimizations that move code around. In the Production target, set the optimizer level to whatever you want. Note that code may be moved around by the higher level optimizations. Jon
what is the compiler and linker DOS commandline options for no optimization? Erik
"In a nutshell, you can create a project with 2 targets" The trouble is, they are totally independent Targets - there is no way to maintain options which need to be common to both. :-( There needs to be (at least?) one more level in the Project Hierarchy.
OPTIMIZE(0)
OPTIMIZE(0) linker and/or compiler ? Erik
Compiler Only. Jon
