WIDTH 16 puts all console text at 2x scale. WIDTH 8 makes it normal again (or ACLS, whichever you prefer.)
Making a file with x number of lines is actually one line of code: SAVE "TXT:FILE",CHR$(10)*x
And it is worth noting, Any file larger than 1048576 characters (or 2MiB) will give a "not enough memory to load" dialog. The first 1048576 characters will be loaded and the rest will be ignored.
