String Processing in ABAP Release 7.55 ITOC
ABAP_MODIFICATION_NN Support of Perl Compatible Regular Expressions
Besides the existing support of POSIX regular expressions, ABAP supports now also PCRE regular expressions that are processed by the PCRE2 Library implemented in the ABAP Kernel . PCRE regular expressions can be used in the same way as POSIX regular expressions. The distinction is made:
By the new addition PCRE that can be used instead of REGEX in the statements FIND and REPLACE.
By the new argument pcre that can be used instead of regex in built-in functions.
By new (factory) methods of the system classes CL_ABAP_REGEX and CL_ABAP_MATCHER. PCRE regular expressions are more powerful and have better performance than POSIX regular expressions. For more information, see Regular Expressions.
ABAP_MODIFICATION_NN Verbatim Replacements
The new addition VERBATIM of the REPLACE statement causes all characters of the replacement string to be taken literally. With that addition, special characters for regular expression replacement patterns have no special meaning.
ABAP_MODIFICATION_NN New Catchable ExceptionCX_SY_STRING_SIZE_TOO_LARGE
See Exception CX_SY_STRING_SIZE_TOO_LARGE in Transformations.
ABAP_MODIFICATION_NN Exception CX_SY_STRING_SIZE_TOO_LARGE in Transformations
The exception that occurs when an operation with a string exceeds its maximum size is now connected to the exception class CX_SY_STRING_SIZE_TOO_LARGE and can be handled. Previously, it always resulted in runtime error STRING_SIZE_TOO_LARGE. This exception can also be handled for the statement CALL TRANSFORMATION if some conditions are met.
ABAP_MODIFICATION_NN Formatting Option CURRENCY for Decimal Floating Point Numbers
The
addition CURRENCY of the WRITE TO and WRITE statements
formatting option CURRENCY in string templates can now also be applied to decimal floating point numbers.
