Info

@DEFINE 134 z/TPF Program Management control statement section; that is, only the specific location is searched for the CTKX component. If the CTKX component is not found in the specific location, an error occurs. CWD is the value specified for the CWD parameter in the @DEFINE control statement section. If you do not specify a default location or a specific location, this is the only location that is searched. CTKX loads the image pointer record (CTKX) to the z/TPF system. When a new copy of CTKX is loaded, it is compared to the existing version. If the starting ordinal of a core image record (CIMR) or IPL component is different in the new copy of CTKX, or the allocated size is too small, that component must also be loaded. version is the 1- to 2-character alphanumeric version code for the CTKX component. .ext specifies an extension of the full program name as created by the linker, where ext is the appropriate extension. For example, if the linker creates a program called ctkx51.so, the .so portion of the name is optional. (progcmt) appends a comment to the CTKX component that is displayed in the output report, where progcmt is the text appended. @@CTKX patches the image pointer record (CTKX). Note: You must load the image pointer record (CTKX) in the current @CTKX control statement section before you can patch it. rsa is the 1- to 6-digit hexadecimal relative starting address in the CTKX component. The relative starting address specifies the offset into the CTKX component where the patch will be applied. newdata is the new data (or patch) that will replace the old data in the CTKX component, beginning at the relative starting address. The new data must be an even number of hexadecimal digits and cannot exceed 32 digits (16 bytes). valdata-olddata validates the data that is replaced by newdata, where olddata is an even number in hexadecimal format that does not exceed 32 digits (16 bytes). The data specified for olddata must match what is currently in the component. If it does not, the data in the component is not changed and an error occurs. If it does, the data in the component is replaced by newdata. For example, this parameter can help to verify that your patch is starting at the correct relative starting address. Note: The length of the data that you are validating can have fewer bytes or more bytes than the new data. If the validation is completed successfully, only the number of bytes in your new data will be replaced. Use the @DEFINE control statement to define system settings.
The following figure shows the syntax for the @DEFINE control statement section of the loader input file. In this figure, the double arrowhead (►►) indicates that the information must begin on a new line. ►► @DEFine ►◄ Note: This must be the first line of the @DEFINE control statement section. ►► (1) ▼ &searchpath= ▼ : (2) path &previouslydefinedsearchpath Notes: 1 If you have more than one search path to define, use this line as many times as you need. Each time you use it, start the next occurrence on a new line. 2 The definition of a search path can span more than one line. To continue on a new line, end your current line with a colon (:), which indicates there is more information in the definition. ►► ►► CWD=path SYSID=bssname SYSID=ssname Figure 15. @DEFINE control statement section of the loader input file z/TPF offline loader input file control statements 135 ►◄ ►◄ ►◄
