Allocating External Files

Using the TSO Allocate Command to Allocate External Files

The syntax of the TSO ALLOCATE command is

ALLOC FILE(ddname) DA('data-set-name ') options

options include options such as file disposition as well as options that describe the format of the file.

Here are some examples:

Allocating an existing member of a PDS:
```
alloc fi(in1) da('my.pds(mem1)') shr
```

Allocating a new sequential data set:

alloc fi(report) da('library.report.feb08')
   new sp(1,1) cyl lrecl(80) recfm(f b)
   blksize(6160)

Concatenating sequential data sets:

alloc fi(input) da('library.data.qtr1' 'library.data.qtr2' 
   'library.data.qtr3' 'library.data.qtr4') shr
