 * Release Version: 1.0.8.4

 * Reference abap language documentation (abap 7.1) : http://help.sap.com/abapdocu/en/ABENABAP_INDEX.htm

 *

 * ABAP syntax is highly complex, several problems could not be addressed, see TODO below if you dare ;-)

 * Be aware that in ABAP language, keywords may be composed of several tokens,

 *    separated by one or more spaces or carriage returns

 *    (for example CONCATENATE 'hello' 'world' INTO string SEPARATED  BY ' ')

 *    it's why we must decode them with REGEXPS. As there are many keywords with several tokens,

 *    I had to create a separate section in the code to simplify the reading.

 * Be aware that some words may be highlighted several times like for "ref to data", which is first

 *    highlighted for "ref to data", then secondly for "ref to". It is very important to

 *    position "ref to" after "ref to data" otherwise "data" wouldn't be highlighted because

 *    of the previous highlight.

 * Control, declarative and other statements are assigned URLs to sap documentation website:

 *    http://help.sap.com/abapdocu/en/ABAP<statement_name>.htm

 *

 * 2009/02/25 (1.0.8.3)

 *   -  Some more rework of the language file

 * 2009/01/04 (1.0.8.2)

 *   -  Major Release, more than 1000 statements and keywords added = whole abap 7.1 (Sandra Rossi)

 *   - in DATA data TYPE type, 2nd "data" and 2nd "type" are highlighted with data

 *     style, but should be ignored. Same problem for all words!!! This is quite impossible to

 *     solve it as we should define syntaxes of all statements (huge effort!) and use a lex

 *     or something like that instead of regexp I guess.

 *   - Some words are considered as being statement names (report, tables, etc.) though they

 *     are used as keyword in some statements. For example: FORM xxxx TABLES itab. It was

 *     arbitrary decided to define them as statement instead of keyword, because it may be

 *     useful to have the URL to SAP help for some of them.

 *   - if a comment is between 2 words of a keyword (for example SEPARATED "comment \n BY),

 *     it is not considered as a keyword, but it should!

 *   - for statements like "READ DATASET", GeSHi does not allow to set URLs because these

 *     statements are determined by REGEXPS. For "READ DATASET", the URL should be

 *     ABAPREAD_DATASET.htm. If a technical solution is found, be careful : URLs

 *     are sometimes not valid because the URL does not exist. For example, for "AT NEW"

 *     statement, the URL should be ABAPAT_ITAB.htm (not ABAPAT_NEW.htm).

 *     There are many other exceptions.

 *     Note: for adding this functionality within your php program, you can execute this code:

 *       function add_urls_to_multi_tokens( $matches ) {

 *           $url = preg_replace( "/[ \n]+/" , "_" , $matches[3] );

 *           if( $url == $matches[3] ) return $matches[0] ;

 *           else return $matches[1]."<a href=\"http://help.sap.com/abapdocu/en/ABAP".strtoupper($url).".htm\">".$matches[3]."</a>".$matches[4];

 *           }

 *       $html = $geshi->parse_code();

 *       $html = preg_replace_callback( "£(zzz:(control|statement|data);\">)(.+?)(</span>)£s", "add_urls_to_multi_tokens", $html );

 *       echo $html;

 *   - Numbers followed by a dot terminating the statement are not properly recognized
