+# Hello,
+# 
+# while doing some experiments with the gawk(4.1.1) i was found problem in implementing character \x00 inside regexp for two cases:

+# str~/\0/
+# 
+# and
+# 
+# switch ( str ) { case /\0/: ... }
+# 
+# the following code try to match given string(=="\x00") with the regexp /^\0$/ using different ways provided by gawk:
+# 
+func	_chm(t) {
+	_ch("match()",match(t,/^\0$/))
+	_ch("split()",split(t,A,/^\0$/)>1)
+	_ch("patsplit()",patsplit(t,A,/^\0$/))
+	_ch("gsub()",gsub(/^\0$/,"&",t))
+	_ch("sub()",sub(/^\0$/,"&",t))
+	_ch("gensub()",!gensub(/^\0$/,"","G",t))
+	_ch("str~/rexp/",t~/^\0$/)
+	a=0; switch ( t ) { case /^\0$/: a=1 }; _ch("switch-case //",a) }
+
+func	_ch(fn,bool) {

+# 3. fine. do you know what situation with the dynamic regexps? no?

+# 
+# i'm asking: WHO will perform testing other cases? You? gawk-team? the God?

+# it's looks like with the dynamic regexp the same story.
+# 
+# i found another one moment that is possible near with the reason of this issue:
+# 
+# i was testing what characters can be present in doublestring and regexp "directly" (just as the character) and what characters must be present as escape sequence (\qqq)
+# 
+# so, i found the following:
+# 
+# t="abc"
+# if ( match(t,/^abc[NUL]def/) ) ... - where [NUL] is the character \x00 
+# 
+# it's seems that in that case the regular expression is processed until [NUL]character and the other part is ignored because the example above gives TRUE
