 ==== Scenario 2: multiple heredoc parsing ====
 
+Consider the following input:
+
+{{{
+
+.sub main
+   foo(<<'A', 42, <<'B', <<C')
+heredoc text a
+A
+heredoc text b
+B
+heredoc text c
+C
+
+.end
+
+}}}
+
+Now, scanning up to and including the first heredoc marker:
+
+{{{
+    foo(<<'A'
+}}}
+
+is done exactly the same as described in Scenario 1. Assume that the lexer just found the heredoc delimiter for heredoc string A. The lexer's current state is HEREDOC_STRING, but as can be seen in [source:/trunk/compilers/pirc/src/hdocprep.l#L404 line 404], the lexer will now switch to SCAN_STRING state in order to scan the "rest of the line". The rest of the line buffer contains:
+
+{{{
+   , 42, <<'B', <<'C')
+}}}
+
