> you can't renumber sections of lines. In some BASICs you can. And where not, there's renumber utilities. Also: MSX-BASIC has the option to save a program in ASCII format (non-tokenised).

Then as it began to take shape, add line numbers manually (replacing the labels). But yes, line numbers are ugly.
