132 z/<strong>TPF</strong> <strong>Program</strong> <strong>Management</strong><br />
Note: You must load SIGT in the current @CIMR control statement section<br />
before you can patch it.<br />
@@USR1<br />
patches the first user-defined CIMR area (USR1).<br />
Note: You must load the USR1 in the current @CIMR control statement section<br />
before you can patch it.<br />
@@USR2<br />
patches the second user-defined CIMR area (USR2).<br />
Note: You must load the USR2 in the current @CIMR control statement section<br />
before you can patch it.<br />
@@csect<br />
patches the specified CSECT in the control program, where csect is the<br />
6-character alphanumeric name of the CP CSECT (for example, CCNUCL).<br />
Note: You must load the control program in the current @CIMR control<br />
statement section before you can patch a specific CSECT.<br />
rsa<br />
is the 1- to 6-digit hexadecimal relative starting address in the CIMR component<br />
or CSECT. The relative starting address specifies the offset into the CIMR<br />
component or CSECT where the patch will be applied.<br />
newdata<br />
is the new data (or patch) that will replace the old data in the CIMR component<br />
or CSECT, beginning at the relative starting address. The new data must be an<br />
even number of hexadecimal digits and cannot exceed 32 digits (16 bytes).<br />
valdata-olddata<br />
validates the data that is replaced by newdata, where olddata is an even<br />
number in hexadecimal format that does not exceed 32 digits (16 bytes). The<br />
data specified for olddata must match what is currently in the CIMR component.<br />
If it does not, the data in the CIMR component is not changed and an error<br />
occurs. If it does, the data in the CIMR component is replaced by newdata. For<br />
example, this parameter can help to verify that your patch is starting at the<br />
correct relative starting address.<br />
Note: The length of the data that you are validating can have fewer bytes or<br />
more bytes than the new data. If the validation is completed successfully,<br />
only the number of bytes in your new data will be replaced.<br />
Use the @CTKX control statement to load the image pointer record (CTKX) to the<br />
z/<strong>TPF</strong> system.<br />
The following figure shows the syntax for the @CTKX control statement section of<br />
the loader input file. In this figure, the double arrowhead (►►) indicates that the<br />
information must begin on a new line.
