 error message returned to the application in
 the interpreter's result.
 .PP
+\fBTcl_LogCommandInfo\fR is invoked after an error occurs in an
+interpreter.  It adds information about the command that was being
+executed when the error occured to the \fBerrorInfo\fR variable, and
+the line number stored internally in the interpreter is set.  On the
+first call to \fBTcl_LogCommandInfo\fR or \fBTcl_AddObjErrorInfo\fR
+since an error occurred, the old information in \fBerrorInfo\fR is
+deleted.
+.PP
 It is important to call the procedures described here rather than
 setting \fBerrorInfo\fR or \fBerrorCode\fR directly with
 \fBTcl_ObjSetVar2\fR.
