The Change User Space (QUSCHGUS) API changes the contents of the user space (*USRSPC) object by<br />
moving a specified amount of data to the object. This API allows you to change the contents of a user<br />
space if you are using either:<br />
● A language that does not support pointers<br />
● System-domain user spaces<br />
Note: To determine the starting position for the QUSCHGUS API, you must add 1 to the offset value. In<br />
contrast to the OS/400 list <strong>APIs</strong>, which use an offset value based on 0 for the starting position, the<br />
QUSCHGUS API uses a value based on 1. For the QUSCHGUS API, the first character in the user space<br />
is at position 1.<br />
