send: zn "namespace"
...
send: set tTaskClassObj = ##class("class name").%New()
send: set tTaskClassObj.<subproperty> = "some value"
send: set tStatus = tTaskObj.AssignSettings(tTaskClassObj)
send: Kill tTaskClassObj
send: set tStatus = tTaskObj.%Save()

As I was using cache terminal this did work for me (and in my case changing namespace was needed as the class was present under that namespace otherwise it was throwing <CLASS DOES NOT EXIST>)

AWESOME!!! @ Eduard Lebedyuk, you saved the day.

And Thanks!! to both Eduard Lebedyuk & Jeffrey Drumm.

I can enjoy my weekend now.

I am actually trying to achieve task creation using Cache Terminal. Here is the bit of the script which does the work for me ..

send: Set tTaskObj = ##class(%SYS.Task).%New()
send: Set tTaskObj.NameSpace = "<NameSpace>" <CR>
send: Set tTaskObj.Name = "<tTaskName>" <CR>
send: Set tTaskObj.TaskClass = "<tTaskClass>" <CR>
send: Set tTaskObj.<subproperty>= "<subproperty>"<CR>
send: Set tTaskObj.Description = "<tTaskDesc>" <CR>
send: Set tStatus = tTaskObj.%Save() <CR>

The highlighted line is suppose that sub-property appears under the Task Type* .

But this is not doing anything helping me achieve the requirement.

How do we specify these extra variables for the task type?

Hi, even having CSPGATEWAYDIR in the package/csp_gateway/parameters file csp is not getting installed in specified directory and keep saying "CSP Gateway: using built-in web server".

So both these below params having no effect.

 ISC_PACKAGE_CSP_SERVERTYPE="Apache"\
 ISC_PACKAGE_CSP_GATEWAY_DIR="/u01/cspgateway"\
