Reserved ABAP keywords

Sometime it is little bit tricky to find out a name for new variable in ABAP until you do not break into a set of reserved ABAP keyword. Basically such a set of reserved words are all the ABAP statements key words, logical operators, data types, predefined functions, etc. According official SAP documentation (see TA ABAPDOCU -> ABAP - By Theme -> ABAP syntax -> ABAP Statements ->ABAP Words) usage of those key words is not forbidden (see picture) we should try avoiding using them. It might happen that there will be some new key words added and your code will not be compatible with further new version of SAP ABAP/Basis/WAS component. 
Therefore while you designing new variable names consider following names as those which are forbidden and you cannot use them as variable names:
