The 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 matrix and general for details about the keywords that can be present in <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
