BINPUTW
Synopsis
Store 32-bit words into binary data object
Description
The BINPUTW stores a specified number of 32 bits words 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 an unsigned binary integer, divided into 32-bits words and the specified number of words is written in the container, in little endian word order;
- a string: the string is converted to a stream of UTF8 codepoints whose lowest 8 bits are zero padded to 32 bits then written in little endian byte order into the container;
- a list of scalars: each number is converted to an unsigned binary integer and its lowest 32 bits are written in the container.
If the size of the source data is less than the specified number of words the writing operation terminates silently without error.
Compatibility
This command is new in newRPL and does not exist in userRPL.
Usage
4: BINDATA 1 AYNcEw 3: 0 2: "X" 1: 1 …………………………………………………………………………………… BINPUTW
where level 4 stores a binary data container of size 4, will result in
1: BINDATA 1 AAAAWQ ……………………………………………………………………………………
a data container storing bytes { #58h #0h #0h #0h } in positions from 0 to 3.
