Addendum: Also examine the possibility of changing your memory model for specific functions, especially infrequently-called functions that have large local variable requirements. Global variables are also to be avoided. Not only are they poor programming practice, but the space that is allocated for a global variable is not overlayed; that is, it is reserved all the time and makes for an ineffecient use of the 8051's already limited resources.
