Greetings.

In $A1 I enter H264. In $A2 I'd like to enter =A1+1, but this won't work
because A1 is a text value. My obvious intended result is that A2 would
display H265 (H264+1=H265). I'd continue with $A3 =A2+1, $A4 =A3+1, etc.
This way I can enter a text value that ends in a number in $A1 and let the
other fields increment the value without any further interaction.

TIA,
