first in its symbol tables for program-defined symbols and internal variables (which includes register names). If a match is found, the matching value is used, otherwise the character sequence is taken as a number. You can force the numeric interpretation by putting a “ 0x” or “ 0X” prefix in front of the number, such as “ 0xb3”. It is undefined whether Ski searches the symbol table for program-defined symbols before or after the internal variable symbol table. Because of this, it is wise to avoid naming global variables and functions with names duplicating any of Ski’s internal variables. In practice, this means you should avoid using register names as names of variables and functions in your programs.
