C51: 256 GLOBAL SYMBOLS LIMIT
Information in this article applies to:
- C51 Version 5.50
QUESTION
In Appendix D of the C51 Compiler User's Guide (01.97), it states that the C51 compiler has a limit of 256 global symbols. Is this per source file or per project?
ANSWER
This is per source file and a limitation of the Intel Object Module Format (OMF-51). The format allows for one byte per source file to hold the number of global symbols.
Typically, one symbol equates to one global variable, however, a structure also equates to one symbol.
MORE INFORMATION
- Refer to D. Compiler Limits in the Cx51 User's Guide.
