In DFSORT Application Programming Guide:
INCLUDE Control Statement
Regular expressions
...
Two versions of regular expressions are supported:
• Basic Regular expressions (BRE)
• Extended Regular expressions (ERE)
Regular expressions can be made up of normal characters
or special characters, sometimes called metacharacters.
Basic and extended regular expressions differ only in
the metacharacters they can contain.
The basic regular expression metacharacters are:
¬ $ . * \( \) [ \{ \} \
The extended regular expression metacharacters are:
|¬$.*+?()[{ }
How can the programmer select which of the two supported
versions DFSORT will use? The later examples seem to show
only EREs or to be neutral. An example showing a BRE
instead would be useful.
Should I submit a RCF?
