The f command files the dual Editor buffers so that additional changes may be made to an item, or to review previous changes. After filing, the line pointer is positioned to the beginning (top) of the item. Changes to items must be made from the top down. This means that changes may not be made to any line above a line that a change has already been made without previously using the f command.
Syntax
f |
Description
As a general rule, use the f command whenever changes are required above the last line that a change was made, or upon receiving a seqn? error message.
Example(s)
The most common error message is the seqn? message. It indicates that a change is being attempted to a line above a line that a change has been made. To correct this, use the f command, then try the same operation that previously failed.
014 print customer-ID .i print f .12 012 print curr.bal .i seqn? |
