	variable and backslash substitution on this string and then evaluating

	command, variable, or backslash substitution took place. foreach of
	these subs, a new guy concatenates 


tclParse.c:ParseVar() - printf on the getvar
tclInt.h:

	parsed. will be altered in ParseWords. will be printed in Tcl_Eval()
tclBasic.c:Tcl_Eval() - printf on command to be invoked
