Table testing with loop

[h3lm3t]

Hi there, i want tto ask your opioion to see if something is possible.

I would like to test the limits of my tables within the database.
Is it possible to use code that started with a single character "a", insert that into a table, then loop through until the valid limit is reached ?

Like:
a
ba
cba
dcba

ive tryed to code this, but VBA is new to me and i'm not sure if im going about it the right way.

Any thoughts, opinions?

thanx in advance
