The EXIT routine causes normal program termination and optionally
returns an exit-status code; the format is as follows:
CALL EXIT (status)
where status is an INTEGER*4 or INTEGER*2 argument containing a status
code.
TIME
The TIME routine returns the current time in hours, minutes, and seconds;
the format is as follows:
CALL TIME (clock)
where clock is a variable, array, array element, or character substring; it must
be eight bytes long. After execution, clock contains the time in the format
hh:mm:ss, where hh, mm, and ss are numerical values representing the hour,
the minute, and the second.
MVBITS
The MVBITS routine transfers a bit field from one storage location to
another; the format is as follows:
CALL MVBITS (source,sbit,length,destination,dbit)
