Hi,

   In z/OS V1R6.0 UNIX System Services Command
Reference(SA22-7802-06,http://publibz.boulder.ibm.com/epubs/pdf/bpxza550.pdf)
page 30-31, it shows an example for literal strings as regular
expressions.
----------------------------------
Note: When you use literal strings as regular expressions, you need
extra backslashes to escape regular expression metacharacters, because
the backslash is also the literal string escape character. For example
the regular expression:

/e .g\7./ 

when written as a string is:

"e .g .."
----------------------------------
   What does "\7" means? Who will be so kind to give me more detailed
description for the above awk regular expression example? Thank you
very much!

Best Regards,
Xie Bo
