Purpose
A deprecated routine now replaced by DBCHUE.
Interface
This routine is called with the following parameters, stylistically presented (the actual syntax varies according to the programming language being used):
DBCHUEC(ReturnCode,ContextArea,UserECB)
In high-level languages, the details of the parameter list are handled by the compiler. For Assembler, the parameter list consists of contiguous 4 byte entries, each containing the 31 bit address of a parameter. The last address has the first bit set to one to indicate the end of the list.
The parameters for this routine are:
| Argument | Content |
|---|---|
| ReturnCode | A 4 byte unsigned integer field into which the return code will be placed by CLIv2. |
| ContextArea | A 4 byte unsigned integer field for internal use by CLIv2. |
| UserECB | The application allocated area for use as the User ECB. For CICS applications, the User ECB must be in SHARED storage. |
Usage Notes
- The DBCHUEC routine does not itself wait for completion of any event.
- The user ECB may be canceled by specifying a User ECB address of binary zeroes.
