Done Help for SET to include @ExecStr[] hint

[TonyT]

Redirected output does not work with SET. e.g.
Echo %_Day | Set Day=%@Line[con,0]
does NOT work because it gets set in a child (pipe) instance and
environment variables are not propagated back to the parent.

use instead for example
Set Day=%@ExecStr[Echo %_Day]

Please add this in the help file ... this problem confounded me forever ... until vefatica enlightened me.

hint

Alternatively, you can use in-process pipes
with the caveat that in-process pipes are not supported in TCC/LE.

Echo %_Day |! Set Day=%@Line[con,0]
