Array of Strings and in and out of 'out of memory jail'

@DrAzzy, you are absolutely correct... the strings are way more substantial than algorithmic derivable values. The actual strings are shown in the code snippet below, which also includes the join-split and store operations in the ini() method. The 'KeyNMO'-thing was just a placeholder to imply that there are many of those - relatively short - strings. I did run out of memory when the strings in 2nd and 3rd block - which correlate - were less then half in count. The characters in the string are encoded values. The encoding is preliminary - but human readable and quick to interpret - and the encoded (unsigned) integer values are in ranges from 0 to 16, 32, and 96. I'm thinking of running them through a generator to compact them even more, and then use them as typed arrays. It would be interesting to elaborate on various implementations and the overall impact - not just in regard of the 'data and its structure', but also the dependent algorithms and their performance. For runtime - after initialization - the values are neededas individual addressable items. At one time I thought I could leave them as complete strings (joined) and access with .substr()... May be it will become possible after compacting them and then 'pay a bit more for it' while repeatedly extracting values. At a later time in the project I will be a more verbose about the strings' purposes.
