Re: C-Strings and LCB
In LCB a string is a string and a number is a number - there's an operator which tests whether a string 'looks like' a number and can optionally convert it. Strings in LCB are the same as in LCS - counted and not nul terminated (so they can contain the NUL 'char' - i.e. Code 0). It does have 'bridging' string types which are nul terminated - they are there to support calling a foreign functions which use such strings. Warmest Regards, Mark.

C-Strings and LCB
I'm not sure why I'm asking these questions because I don't think I really understand them . . . 1. Does LCB differentiate between numeric variable and string variables (those that contain text)? 2. If so, are LCB string variables null-terminated?
