Change User Space (QUSCHGUS) API
Required Parameter Group
Qualified user space name
INPUT; CHAR(20)
The first 10 characters contain the user space name, and the second 10 characters contain the name
of the library where the user space is located. The special values supported for the library name are
*LIBL and *CURLIB.
Starting position
INPUT; BINARY(4)
The first byte of the user space that is to be changed. It must have a value greater than 0.
Length of data
INPUT; BINARY(4)
The length of the new data in the input data parameter. The length must be greater than 0.
Input data
INPUT: CHAR(*)
The new data to be placed into the user space. The field must be at least as long as the length of data
parameter.
Force changes to auxiliary storage
INPUT; CHAR(1)
The method of forcing changes made to the user space to auxiliary storage. The valid values are as
follows:
0
Does not force changes. Normal system management writes the changes to auxiliary storage.
1
Forces changes asynchronously. This interrupts the normal system management and ensures
that the user space is written to auxiliary storage.
2
Forces changes synchronously. This interrupts the normal system management and ensures
that the user space is written immediately to auxiliary storage.
Optional Parameter
Error code
I/O; CHAR(*)
The structure in which to return error information. For the format of the structure, see Error Code
Parameter. If this parameter is omitted, diagnostic and escape messages are issued to the
application.
