File structure question
(First off let me apologise for the somewhat rambling nature of this
I currently do a lot of work in THEOS MultiUser BASIC. That has one type
of file that I find incredibly useful - ISAM files. The format for one
You create one thusly:
CREATE JIM.DATA (INDEXED KEYLEN 10 RECLEN 200
which would create an ISAM file called 'JIM.DATA' with a key length of
50 chars and a record length of 200 chars.
Writing to one is simply a case of opening it and writing like this:
and reading from it would be a case of:
READ #1,"KEY":VAR1$,VAR2$,VAR3$ (doesn't have to be strings)
you can also do things like:
which would read the next key in the file (based on current position)
I'd like to move a lot of this stuff over to an Objective-C environment
(probably on a Mac, so with the Cocoa libraries) but my question is
simply: is there an easy-ish way to duplicate the ISAM file behaviour
using Obj-C and the Cocoa libraries?
