In that case you'll want to use %Net.SSH.Session to connect to the site and once signed in use the OpenSFTP method to open a SFTP session to be able to make %Net.SSH.SFTP calls, in particular the Put or PutStream method
 

Use $ZDATEH() to convert to internal $HOROLOG format, and $ZDATE() to convert to your desired format

WRITE $ZDATE($ZDATEH("14JAN1991",8),8)

type
KILL
DO ^%IS
hit Enter twice
WRITE

and look at what IOF and IOST are set to

SET Command="wmic useraccount get name,sid"
SET $ZT = "CommandErr"
OPEN Command:"QR"
FOR {
USE command
READ Text
USE $P
SET Array($I(Array))=Text
}
CommandErr ;
SET $ZT=""
SET ZE=$ZE
USE $P
CLOSE command
IF $P(ZE,">")'="<ENDOFFILE" {
; some error other than end of file
}
ELSE {
; parse contents of Array()
}

If the command you're using doesn't support redirection to a file use a command pipe
e.g.
SET $ZT="CommandErr"
OPEN Command:"QR"
FOR {
USE Command
READ Text
USE $P
; do something with the text
}
CommandErr ;
SET ZE=$ZE
SET $ZT=""
USE $P
CLOSE Command
IF $P(ZE,">")="<ENDOFFILE" {
; successful completion
}
ELSE {
; something happened
}

You could try using $QUERY to iterate the global and use $QLENGTH to determine how deep you are and $QSUBSCRIPT to determine what the subscripts are.
