Looping counter

Create an infinite loop that outputs lines of asterisks, with each line containing one more asterisk. Instead of the asterisk, any printable, non-whitespace character can be used. However all lines need to use the same character.

The beginning of the output looks like this:

*
**
***
****
*****
******
*******
********
*********
**********
***********
************

An ungolfed Python implementation:

from itertools import count

for i in count(1):
    print('*'*i)

Embed ESCR, about 32 characters depending on how you count

loop
  append s "*"
  show s
  endloop

The indentation is not required, but shown for clarity. Declaring the variable S is also not included, since similar stuff doesn't seem to be included in other examples.

S is a string variable. In ESCR, storage for a string can grow dynamically at run time as needed. The string initialially starts empty, with one "*" appended to it each iteration.
