Interesting point Evil Consultant. Thanks for the info.After reading about acronyms and initialisms on wikipedia, I understand that the difference between the two is bit of a grey area.
The funny thing is acronym S.A.P has a german origin and stands for 'Systemanalyse und Programmentwicklung' ("System Analysis and Program Development"). Suits perfectly as an acronym (as per the defination of acronym -source wikipedia).
Later, however, the acronym was changed to 'Systeme, Anwendungen und Produkte in der Datenverarbeitung ("Systems, Applications and Products in Data Processing"). Now it fits for 'initialism'
Anyways, without deviating from the main question,i.e, S.A.P or 'sap', please note the following quotation and presumably the reason why S.A.P company itself doesn't want their company name to be pronounced as 'sap'.
