Macro needed for copy paste!

[rukia]

Hi everyone,

Here is my scenario.

A = Column, 1 = Row

A1 = X
A5 = Y
A19=Z
A24=ZXCV

Is there a macro whereby I can fill up A2 - A4 with A1 (X), fill A6-A18 with A5 (Y), and fill A20-A23 with Z?

Not sure if copy+paste, or autofill will help.

Any help will be much appreciated.

Thanks,
Rukia
