Individual BCAM settings can be made with the DCSTART, DCOPT, BCMOD, BCOPTION, MODIFY-BCAM-OPTIONS and BCTIMES commands. These settings remain in effect for different periods of time and can be subdivided into two groups:
The first group, which appears in the "BCAM session (1)" table below, includes operands that revert to their default values following a BCEND command and a new DCSTART. These operand settings are thus valid only for the current BCAM session.
The second group, which appears in the "BS2000 session (2)" table that follows, includes operands that retain any set values which differ from the defaults even after a BCEND command.
