TSO environment

In the TSO environment, use one of the following to specify the Trace Resolver output location:

For the user's terminal, enter the following:
```
alloc dd(systcpt) da(*)
```
When directing Trace Resolver output to a TSO terminal, define the screen size to be only 80 columns wide. Otherwise, trace output is difficult to read.
For an existing MVS™ data set, enter the following:
```
alloc dd(systcpt) da(appl.restrace)
```
The user ID is used as the first qualifier for the data set. For example, if TSO USER1 entered the above command, user1 would be appended to the data set, as shown below:
```
alloc dd(systcpt) da('user1.appl.restrace')
```
To disable the Trace Resolver output, enter the following:
```
free dd(systcpt)
```
