a solution with NO $TRANSLATE

 set str="aN d.ef123$eR=xx?,yWz"
 for i=1:1:$l(str) s:$e(str,i)'?1(1AN,1".",1" ",1",") $e(str,i)=" " 

 aN d.ef123 eR xx ,yWz

use instead.

set ID=##Class(User.School).%OpenId(RollNo_"||"_Marks,,.sc)

do $system.OBJ.DisplayError(sc)

now you should see the reason why  ID=""

Load your properties into local variables and it should work

the DEFAULT function of # for a terminal window emulating a CRT ist hardcoded.

see Terminal I/O WRITE

"Issuing WRITE # to a CRT terminal clears the screen and sends the cursor to the home (0,0) position."

using a Mnemonic Definition you may supply the required escape sequence to cover your needs.

but instead of WRITE #  you may need to use  WRITE /TOP  (just as an example)

For all about Mnemonics see Controlling Devices with Mnemonic Spaces.

you operate not on document object but on zenPage object

see docs:  Client Side Functions, Variables, and Objects  at the beginning >>>

• Find a Zen component by id value. Returns the object that matches the input id.

• The zen(id) JavaScript function is equivalent to the following client-side JavaScript method call on the page object:

• zenPage.getComponentById(id)

• You can use the zen(id) function wherever JavaScript syntax is appropriate; 

In namespace %SYS you have the utility  ^JRNDUMP  which displays the content of journal files in "readable" text format.
You may need to adapt it to your requirements.

Depending on your activities in the DB  this may take many many GB !
I'd suggest examining the content first from Mgmt Portal to see if this is what you expect. 

did you verify if  par2 is really "0912" (leading zero) and not just 912
