41C X-Mem data file editor?

[rprosperi]

It's interesting that after all these years, this is a rather obvious application that either was never created, or if it was, never got wide enough distribution that any of the still active members here know about it. More than likely, there is something like this buried in the PPC/CHHU Journal issues, but writing this from scratch may be less work than searching through all that.

For navigating (next record, insert/del record, etc.), I suggest you copy the key assignments (or mappings) from ED, as much of that can be the same; no need to invent something new when those keys are documented right on the device. The key difference is data files can have multiple 'fields' per record, rather than single lines of text, so some clever paradigm for moving 'horizontally' is needed. If each field will be replaced (rather than edited) you could use the [USER] and [PRGM] keys the same way these advance through a text file.
