On a PC (where TurboC, FoxPro, dBase run) the default MDA/CGA/EGA/VGA
screen is 80x25.

Nothing to do with whatever language you use. That is a (miss-)feature
of your terminal (or display drawing driver/library on a PC).

Good terminals have an virtual 81st character, to which they position
the cursor after printing on the 80th column. If there then they
linebreak/scroll only when the next character arrives. If annother
positioning command comes before the next character, then no
linebreak/scroll happens.

PC display drivers (such as ANSI.SYS) and libraries (such as used by
TurboPascal, TurboC, dbase, etc) should emulate this behaviour. Some
do not. That is vendor specific brokenness, not language specific.
