Detailed string highlighting

Strings are highlighted as composed of an opening delimiter (a single or a double quote), a string contents (which may be empty), a closing delimiter, and an optional suffix.

string := delimiter contents delimiter [suffix]

The delimiters and the suffix are highlighted according to the .EL.STRING_OPENING_DELIMITER, EL.STRING_CLOSING_DELIMITER and EL.STRING_SUFFIX element categories, and the string contents according to the corresponding string element category.

Say "This is a string with a suffix"T

Please note that the Rexx Parser returns a single element to represent the whole string; the Highlighter uses the categories above to introduce more detail and to improve the highlighting results.

When the string is neither a binary string, nor hexadecimal string or a Unicode U-string, and the contents of the string represent a number (that is, if the DATATYPE built-in function returns "NUM"), then the contained number is also highlighted, according to the rules defined in the documentation about detailed highlighting for numbers.

Say " + 1234.5678e-1027  "    -- Highlighting of a number inside a string
