Screen Editing

[someone]

I was just wondering if there is any way of editing anything already
printed on the screen with out using the system("cls") command.

I agree with you vis-a-vis '\f', but my reply above was an
attempt to paint a larger picture---that it is indeed possible to
``edit'' something that is already written on the screen, if not
by '\f', then by '\r' or '\b' on the current line.

An interesting discussion. But when I go back to what the OP posted
it has gone a bit off-topic. And to get more off-topic, I have used
a full-screen editor that worked across half-duplex lines, so it was
only when you entered a CR that the base system knew what you had been
doing. (FSE under NOS/VE on CDC Cybers.)

(WRT clearing the "screen")

For some reason, no one liked this suggestion of mine when I
brought it during the last discussion of this issue:

for (;;)
putchar('\n');

How about

{
int idx, times=1;
while( 1 ) {
for( idx=0; idx < times; idx++ ) {
putchar( '\n' );
}
printf( "Was that enough?\n" );
if( getc(stdin) == 'n' ) {
times++;
continue;
}
break;
}
}

? This way the programmer can decide when the screen is clear enough,
assuming of course I haven't made any silly mistakes.
