F - Flip

Toggles the Editor buffers.

Syntax

F

Operation

F updates the Editor's working copy of the item, renumbers its lines, and sets the line pointer to the top of the item.

Multiple String Replacements on a Single Line

You can perform multiple string replacements on a line without issuing an F command. For example,

003 CAT
.R/CAT/DOG Return
003 DOG
.R/DOG/RAT Return
003 RAT
.

You can modify the last line of an I(nput) or ME(rge) sequence in the same way as many times as is necessary.
