DGADTDYN Parameters
The RUN TASK command invokes DGADTDYN with parameters that define allocation actions to execute. The following rules apply to the syntax of the parameters:
- Perform each allocation action with as many parameters as required.
- Separate each unique allocation action by a parameter containing a fullword of minus one (F'-1').
- A leading blank on the first parameter is not required; however, you must include a leading blank on all subsequent parameters. If you do not include a leading blank, the program issues an RC=30 and an SRTA005I message for the Process.
- Parameters must not extend past column 72, or they are not read.
The following table shows the available dynamic allocation functions:
Function | Description |
ALLOC | Use the ALLOC function to allocate a file. The allocation request can contain most job stream DD statement options, including DCB options applicable to allocation. This function is the default. |
UNALLOC | Use the UNALLOC function to unallocate a file. |
CONCAT | Use the CONCAT function to concatenate two files. |
DECONCAT | Use the DECONCAT function to perform dynamic deconcatenation. |
LOCATE | Use the LOCATE function to locate cataloged data sets. |
Note: You cannot access HFS files using DGADTDYN.
