The `set datafile binary` command is used to set the defaults when reading binary data files. The syntax matches precisely that used for commands `plot` and `splot`. See `binary` for details about <binary list>.
Syntax:
set datafile binary <binary list>
show datafile binary
show datafile
unset datafile
Examples:
set datafile binary filetype=auto
set datafile binary array=(512,512) format="%uchar"
show datafile binary # list current settings
