Another, even easier way to bring in any editing-comments is, to type in any sort of normal umess-comment, such as TEXT, BTEXT or BEDTEXT (1676,1677,1678) and to set the line-counter in the first text line, column 4, to zero. This is similar to 'masking' a block of controllines. The text still is in your control data but will take no effect during a program run.
