Yes, it does. See AN833 (DS00833B) Section "Stack Configuration" on page 3, second column, line 4: "Most of these are defined in the header file StackTsk.h. Some defines that are defined other files are shown with correponding file name.". This refers to table 1, "Stack Configuration Definitions" immediately below on the same page. What part of this do you find confusing? Even without this explicit mention in the manual, you could easily run a pattern match on all the .h files to find references to a particular symbol. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
