You do not need to trace SVC 99 to figure this out. Most of the answer is in the manual: <quote> DSNAD=dsnad DSN=dsn DDNAME=ddname A required input parameter. DSNAD=dsnad A 4-byte field which contains the address of the area of the name pattern used to create the data set that is to contain the dump. The format of the area is described in the DSN field which follows. To code: Specify the RS-type address, or address in register (2)-(12), of a pointer field. DSN=dsn A 2- to 101-character input area that contains the name pattern used to create the data set that is to contain the dump. The format of the area begins with a single byte specifying the length of the name pattern, which must not be greater than 100. The name pattern immediately follows that byte. The name pattern has a series of attributes: it is similar to that used by the operator DUMPDS NAME= parameter, except that &SEQ is not supported, and there is no default name pattern available; the use of system symbols is supported; and it must resolve to a valid data set name which can be allocated from the caller's task . When used with the REMOTE= parameter, the generated name must be unique for each requested address space (&JOBNAME is one recommended addition to the pattern to accomplish this). In addition, IEATDUMP also recognizes the symbol &DS. (Dump Section) on the end of the name pattern. When present, IEATDUMP allocates the first data set for dumping, ending with "001". If this runs out of disk space or uses up all 16 extents before the dump is completed, dumping will be continued to data sets with the same name, but ending in "002","003", and so on, until the entire dump is written. Each of these data sets are allocated with a primary extent size of 500M and a secondary extent size of 500M, but it is possible to change these values by providing ACS routines that are driven by DFSMS. Remember to combine all of the data sets into one data set by using IPCS COPYDUMP, before using IPCS to view the diagnostic data. To code: Specify the RS-type address, or address in register (2)-(12), of a 2- to 101-character field. DDNAME=ddname An 8-character input field that is the name of the DD representing the data set that is to contain the dump. The DD must be allocated when IEATDUMP is invoked. The system will open this DD. To code: Specify the RS-type address, or address in register (2)-(12), of an 8-character field. <end quote> For the part of the answer that is not in the manual: If the DSN name pattern does not end in &DS (or you are running on a release lower than z/OS 1.10), IEATDUMP creates a 2GB data space, and captures the dump data into that data space (so the maximum size of the dump is 2GB). IEATDUMP then knows the exact size of the dump (the amount of data in used in the data space), and allocates a primary extent of that size. I don't know what LE uses for the DSN name pattern, or if it allows you to specify that in some LE parameter. I am considered to be fairly knowledgeable about z/OS dumping, but I am not an LE user.
