objarray set <obj> {<value_1> ... <value_n>}|<index> <value> | -binary <data> |
objarray set <obj> <index> <value>
Set the value of the item $index (from 0 to n-1) with the value $value, or all values from a list {value_1 ... value_n}.
The value could be the special string “NaN” (not a number) or “Inf” (infinite)
<value> could be a single number or a list of multiple numbers (to set the values of index, index+1, …)
To set some index the array space must be allocated previously with a size greater of the index.
objarray set <obj> {<value_1> ... <value_n>}
Set all values from a list {value_1 ... value_n}.
In fact instead the list could be another objarray of the same length (can be of other type, a casting will be done for each item).
objarray set <obj> -binary <data>
copy directly the bytes of <data>, for example to store the data of an image.
