Resetting switches and flags

Throughout your program, you might need to reset switches or flags to the original values they had in their data descriptions. To do so, either use a SET statement or define a data item to move to the switch or flag.

When you use the SET condition-name TO TRUE statement, the switch or flag is set to the original value that it was assigned in its data description. For a level-88 item that has multiple values, SET condition-name TO TRUE assigns the first value (A in the example below):

88 Record-is-Active Value "A" "O" "S"

Using the SET statement and meaningful condition-names makes it easier for readers to follow your code.
