A specific sequence of commands
is required to get an accurate listing of files.
Initialize
the device by issuing:
! U1 setvar "zbi.program_list" "fill"
To
get the first file, issue:
! U1 getvar "zbi.program_list"
This
will return the current filename in the list of zbi files present
on the E: drive. If the response returned is
"none"
you
have reached the end of the list.
To get the next filename
in the list, issue:
! U1 setvar "zbi.program_list" "up"
To
get the previous filename in the list, issue:
! U1 setvar "zbi.program_list" "down"
To
execute the current zbi filename, i.e. the one returned by a getvar,
issue:
! U1 setvar "zbi.program_list" "execute"
