Keys that Cannot be Defined

Alt key sequences (except as noted in the preceding table), PrtSrcn, and F10 are directly handled by 32-bit Windows and cannot be referenced in COBOL. You can free the F10 key to act as a user defined key by using a configuration variable. Setting the F10_IS_MENU variable to 0 inhibits the standard menu activation capability for the F10 key. See Appendix H for more details.
