BINPUTW
Synopsis
Store 32-bit words into binary data object
Description
The BINPUTW command 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 and divided into 32-bits words which are stored in the container, in little endian word order;
- a string: the string is converted to a stream of UTF8 codepoints whose lower 32 bits are stored into the container;
- a list of scalars: each number is converted to an unsigned binary integer and its lower 32 bits are written in the container.
If the size of the source data is less than the specified number of words remaining words will be set to #00000000h.
Compatibility
This command is new in newRPL and does not exist in userRPL.
