Hi Craig Actually I am very determined to get to a mastery of LC. I understand it takes time. BUT, after 35 plus years working with programming database apps I find it odd that the old HyperCard I used 20 years ago has evolved but not as well documented as was HyperCard of old. Oh yes I know HyperCard was much smaller in scope then, but 30 years have passed since then. I have used a large number of different database programs over the years and judging LC against them I find LC fragmented as to the documentation.
The current database I use is FileMaker Advanced and it is so well documented it is a gem to work with. By the way my expectations was to use LC as a database substitute with IOS and Android. I have had to reassess my goals based on the limits I have seen to date of LC.
