BINPUTB
Synopsis
Store bytes into binary data object
Description
The BINPUTB stores a specified number of bytes into a binary data container, starting from an offset position; it's not possible to write data exceeding the container's size.
The source of data can be:
- a scalar: the number is converted to a positive integer and its lower 8 bits are replicated for a specified number of times into the data container;
- a string: the string is converted to a stream of UTF8 codepoints whose lower 8 bits are written into the container;
- a list of scalars: each number is converted to a positive integer and its lower 8 bits are written into the container.
If the size of the source data is less than the specified number of bytes the writing operation terminates silently without error.
Compatibility
This command is new in newRPL and does not exist in userRPL.
Usage
4: BINDATA 1 A4gACz 3: 0 2: 0 1: 4 …………………………………………………………………………………… BINPUTB
where level 4 stores a binary data container of size 4, will result in
1: BINDATA 1 AAAAAA ……………………………………………………………………………………
a data container totally empty.
