Easily:

    Screen : array (1..24) of String (1..80);

Remember it is either plain text I/O or else not. Plain text ends with 
fixed space ASCII, maybe, some subset of Unicode. Anything beyond that 
is not not text, but a text buffer, document, surface for rendering, 
cell renderer etc. The problem you describe simply is non-existent. 
There is no such thing as column, but some coordinate system, or 
iterator/cursor, or markup etc.
