FILE ACCESS
Parameters that are written in GREY in the command tables are considered optional details, and partially have default values. The default values are
given in brackets behind the corresponding parameters. Parameters written in BLACK on the other hand, must be assigned values. Commands that
may contribute towards changing parameters can only be used if the corresponding parameters have already previously been defined. Some com-
mands allow for entering several object IDs. Should these objects be in numerical sequence, the range may be specified with the “-” sign, e.g. 1-5, instead
of 1,2,3,4,5.
