DRL T.CFIO (octal 77) - command file processing.

Usage:

drl    t.cfio
zero   L(arglist),function number

Description:

DRL T.CFIO supports command file and deferred processing applications. The available functions are listed below by number.

1: This function requests the executive to enter command file processing mode by setting bit 8 of .LFLG2 in the UST. L(arglist) represents the location of a three-word information block containing .LCFIO, .LCFST, and .LCMPT images.
2: This function requests the executive to terminate command file processing by turning off bit 8 of .LFLG2. When deferred processing is in progress, the TERM subsystem is scheduled on behalf of the session and the UST is subsequently released. L(arglist) is not used.
3: L(arglist) represents the location of a 9-word information block to which executive communication region cells .TSDMX through .TSDJB and .TCDFR are transferred. Upon return, the A-register contains the current BCD date (YYMMDD) and the Q-register contains the time of day in increments of 1/64 milliseconds past midnight. If L(arglist) is zero, only date and time are returned.
4: Privileged. L(arglist) represents the location of a 5-word information block that is to be transferred to communication region cells .TSDID through .TSDJB.
5: Privileged. This function shuts the .TSDGT gate and must be used before the deferred queue file or .TSDID-.TSDJB communication cells can be updated. When the gate is already shut on behalf of another user, execution of the DRL is delayed until the gate is open. L(arglist) is not used.
6: Privileged. This function opens the .TSDGT gate. L(arglist) is not used.
7: Privileged. L(arglist) represents the location of a word containing the BCD job identifier (nnnnD) of an executing deferred session that is to be aborted. Bits 30-35 of this word are ignored.
