Hi all,
I have a n00b question.
Is there any facility for reading a line of text from the console,
so we can prompt a user?
I feel certain there must be a way to read a string into a
variable, but can't seem to find one...
Please advise,
Eric

Do you mean in C code, or as CLI command?

The first would be readline(), the second "env ask" (or "askenv").
Best regards,
