Programmable switches consist of a digit in the range 0 through 8. These switches correspond to the COBOL switches that you define in the Special-Names paragraph of your program, enabling you to set these switches on or off when your program begins executing. Any changes made to the settings of these switches using the COBOL statement SET mnemonic-name TO ON or OFF is not effective once the application has terminated. For details of how to use the SET statement with COBOL switches, see your Language Reference.
