Hi, dear All. I have made exhaustive (at least, hope so) search in the documentation and mail list archives but found only that "GPC will align variables according to maximum performance", but how exactly? On what boundary will be aligned Integer, Boolean, Longint, Word, etc. On what boundary will be aligned string, record, array, their elements and are there any differences between default alignment of variable without record and variable as record field? And, if possible, I need information for the other platforms. I understand that I can make experiments to find it out but it seems to me it should appear in one or in other place (GPS manuals or mailing lists). Thanx, dear All. Best regards, Ingvar mailto:marny@rambler.ru
