The cd BASIC program changes the current working directory to the specified new directory. The new directory remains until the D3 process is disconnected (not logged off) or a new cd command is issued. If the new directory is omitted, the default home directory is selected.
The check-dx BASIC program looks through every file on the system to find and identify those that have a dx, dy, or dl in attribute 1 of the D-pointer. The dx and dy files are not saved by the save processor.
The check.pib command displays the PIB information, such as PIB status, virtual return stack, workspace status, any basic programs being executed, as well as locks, peqs, files, items, connections and other objects being used by that PIB.
The chg-device command changes a tape device. Devices that can be used as tapes are listed with the list-device command. Some characteristics can be changed to either modify the behavior of a device or to replace a device by another one. The changes made with this command are not permanent and are lost when the virtual machine is rebooted. If no option is specified, the current value is retained.
The cleanpibs BASIC program clears tandem connects for all ports logged on before port 0. This is used at coldstart time to make sure that any tandem information left over from a system crash does not get picked up.
The clear-locks BASIC program clears all locks, or specific locks, according to the options provided. When used with the i option, an optional host can be specified to release all item locks residing on a remote server.
The coldstart command initiates the sequence of activities that must be performed each time the system is powered on. Additionally, the coldstart command initializes the transaction log queue limit to 0 on a full restore and during a patch installation.
The compile.flash.all command allows you to compile all BASIC programs currently compiled with FlashBASIC, either in one or all accounts on the system. The result is platform independent, optimized object code that does not require the existence of a C compiler.
The create-index BASIC program creates a new B-tree index in the specified file using the a (algebraic) processing code expression provided and ensures the a0 index case-sensitivity matches the item-ID case sensitivity.
The crt-delimiters command enables and disables the display of attribute and value marks. At boot time, the crt-delimiters command defaults to on. If the crt-delimiters command is executed without options, then it displays the current status.
The cvtcpy utility in the DM account copies a tape to another tape, including format and block conversions, and reads D3, CIE, Reality or Ultimate tape formats, with a block size up to 64 KB, and creates a D3 tape.
