SSLNGC08006 2002 ISO COBOL - Enhanced literal continuation support

NOTE 2:
As of the creation of this requirement, the ISO 2014 COBOL Standard has not yet been approved. However, it is expected that it will be approved and published (without any technical changes from its current content) by the end of 2014 and before IBM is likely to respond to this requirement

With the increased maximum data item size in Enterprise COBOL V5.1 and the increased use of large data items for XML processing, it has become even more important that IBM provide support for the technical enhancements for (alphanumeric) literals in the 2002 and 2014 ISO COBOL Standards.

In particular, the following two enhancements should be supported in IBM COBOL

1) Ability to continue alphanumeric literals without paying attention to columns 7 or 72. For example, a continued representation of the literal "ABCD" could be coded as
"ABC"-
"D"
without worrying about where (between columns 8 and 72) these two lines begin or end. This has particular benefits when coding alphanumeric literals that include DBCS characters and where the source may be ported to or from z/OS and Windows or AIX. (Where Shift-Out/-IN characters may change the size of any line containing the literal.)

2) The maximum size of alphanumeric literals has been increased from 160 character positions to 8,191 character positions. When combined with easier literal continuation, this would make processing of some XML documents much easier.
