# $XRef_Full: from one or more source files, build a cross-reference list
#of all top-level terms. The built-in function "lookup" must be
#supported by the application calling hAWK (at present this means just
#EnterAct).  For this to work properly when called from EnterAct, you
#must have a project open, the project must include files which define
#all the terms you wish to cross-reference (include the toolbox headers
#in your project if you want toolbox terms cross-referenced), and your
#dictionary should be up to date.
#Similar to $XRef, but does not skip over comments and strings, so
#"spurious" references may result. Presumably, you'll want them.
#Use "Set variables" when calling this program to specify which kinds
#of terms to include in the cross-reference. There are eight kinds of
#terms, and eight corresponding variables that can be set to 0 or 1,
#eg do_defines=0 means don't include defines, whereas do_defines=1 means
#include defines.
#
#Typically use the “MFS selected files” input option on one or more files.
#Any other input option is also OK, just ensure an appropriate EnterAct
#project is open before running this program.
#
#The array "skipList" (see "XRef_Full.T") holds a list of common terms to skip over.
#In large cross-reference jobs it may be NECESSARY to skip the commonest
#terms to avoid overflowing the list of references.
