Hi;
I am trying to write a function that will insert a line of asterisks+
spaces across a buffer (as a section divider). It was started as an
exercise and has become an exercise in futility.
I am working in the scratch pad using C-j to test the function as it is
being built. I have: (insert "* "). It returns "* nil". Obviously I
don't want the "nil" to appear. How do I get rid of it?
More importantly to me, how do I get the (insert "* ") command to repeat
27 times to give me 54 characters across the buffer? I know how to make
a recursive loop, but it seems to me this is a fairly common challenge
and there is a probably a function for repetition that I can't find.
I suppose I am asking for the programming equivalent of 'C-u n'.
'insert-char' allows for repeating but only one character at a time, not
two.
Any guidance would be appreciated.
