+#print
+You can use '*' to look for a string of characters
+from one of the character classes. Suppose, for example,
+we wanted a long string of either 'a' or 'b', followed
+by 'x'. Then we could write
+
+ s/[ab]*x/.../
+
+In this directory is a file named "table".
+It has only one line. On that line, replace all the digits
+followed by a comma with the letters "too big". For example,
+"123,000" should become "too big,000".
+Then rewrite the file and type "readY".
+#create Ref
+Heathrow too big,159
+#create table
