Anyone know how to add a string to a 1d array with file info, then be able to read back, display string, and sort data array.

Question

I need to store a data array and include text that describes what the data is. (using for various configuration files.) Anyway, I would like to be able to save the string as part of the txt file, and somehow read it back, remove the (various length string), and display it in an indicator. All the while, not causing too much problem with the initial data array.
Thanks in advance!!

There are several ways to do what you require. A simple method would be to use an ASCII text file. When writing one of those, you just need to basically build a gaint string starting with the description text you want. We like to call that a header. Once you've got the header, make some sort of delimiter like a bunch of "-" or two sets of ( EOL = End of Line = CRLF = \r\n ). After your delimiter, concatenate your array in string form or flatten your array from its native form into a string and tack it on the file (append).
See the (very quick) example attached.
