Enhancements in this release
This release provides the following functional enhancements described
in this and the other IBM PL/I books.
- XML generation, by using the XMLCHAR built-in function, now supports
XML attributes and the omission of null values.
- The compiler now explicitly supports some use of adjustable BASED
without REFER.
- The compiler now supports comparisons of POINTER to null strings ('' and ''b).
- The compiler has raised the maximum number of distinct include
files allowed in a single compilation from 2047 to 4095.
- The new BY DIMACROSS form of assignments makes it easier to write
code to handle the results of SQL multi-row fetch.
- The compiler and the preprocessors (rather than just the SQL preprocessor
when parsing EXEC SQL code) now all support <> as a not-equals
symbol.
- The new INDICATORS built-in function makes
it easy to declare an array to be used as an SQL indicator variable
with a structure.
- The new POPCNT built-in function returns
a FIXED BIN value holding in each byte the number of bits equal to
1 in the corresponding byte of x.
