You suppose to use logging command to create Azure Pipelines variable

Write-Host "##vso[task.setvariable variable=testvar;]$data"

and then in next task you can reffer to variable as

$(testvar)

or

$env:TESTVAR

Be aware that Azure Pipelines variable will not be available in the task you will create it. And if you need variable in another job or stage then you need output variable. Here you will find how to use it.
