CHAPTER 18. PREPROCESSOR MANUAL
18.8
Preprocessor libraries
368
This table list all libraries, the user words they provide, their field of application and the registers they use. It is not recommended to use any internal words defined in the library nor to define any words starting with an underscore. Some libraries contain words that are intended to be used inside other macros, others provide new keywords you can use in your programs. Note that not all libraries can be combined. Refer to the source for details.
Some libraries clobber one or more registers. If any of these registers contain meaningful values when you use the library, these values will be overwritten. Save them on the stack before using any of these words or refrain from using these registers yourself.
