Changing information

What if you wrote a report about a product called Whiz and after the report was completed, you were informed that the product name had been changed to Speedo. You can use the FIND command and find each instance of the old name and change it, or you can use the CHANGE command that automatically changes the old name to the new.

The CHANGE command requires two strings. The first is the word(s) you want to change, and the second is the changed word(s). CHANGE can be abbreviated to CHG or C. Thus to change Whiz to Speedo, enter on the COMMAND line:

c Whiz Speedo

The cursor moves to the first instance of Whiz and changes it to Speedo.

If you want to change all occurrences of a string to another string, you can add the word all to the command. To change Whiz every time it occurs in your report to the new name Speedo, enter:

c Whiz Speedo all

==CHG> appears on every line number where a change was made.

To change a phrase to another phrase, enclose the words in single quotation marks. For example, to change the phrase "generally speaking" to "in general", enter:

c 'generally speaking' 'in general'

CHANGE is often used with the RCHANGE PF key (PF 6). For more information about the RCHANGE PF key, see PF keys summary.
