From TO
005 6H Contains the length of the password field for the second corn-
mand-tail operand. The CCP also sets this field to zero if no
password for the second command tail is specified.
0057H - 005BH (Not currently used - reserved)
005CH - 007BH Default File Control Block, FCB, area 1 initialized by the CCP
from the first command-tail operand of the command line, if
it exists.
006CH - 007BH Default File Control Block, FCB, area 2 initialized by the CCP
from the second command-tail operand of the command line,
if it exists.
Note: this area overlays the last 16 bytes of default FCB
area 1. To use the information in this area, a transient program
must copy it to another location before using FCB area 1.
007CH Current record position of default FCB area 1. This field is used
with default FCB area 1 in sequential record processing.
007DH - 007FH Optional default random record position. This field is an exten-
sion of default FCB area 1 used in random record processing.
0080H - OOFFH Default 128-byte disk buffer. This buffer is also filled with the
command tail when the CCP loads a transient program.
