I recently met an ages old issue related to code maintenance:

• You have access to your IRIS server just over ODBC/JDBC
• no VSCode access, no Studio access
• no (Web-)Terminal access

But you need to take a look on Classes or Routines or Globals !!
Anyhow SQL is your friend.

• First you need a simple table as temporary text store.

CREATE GLOBAL TEMPORARY TABLE  arcc.txt (line VARCHAR(32000))

Not a thrilling action.

• Next you export your code to local file and import it to your table

CREATE PROCEDURE arcc.show (IN code VARCHAR()) 
  RETURNS INTEGER
  LANGUAGE OBJECTSCRIPT 
 {
	set file="code.tmp"
	do $system.OBJ.ExportUDL($g(code),file) 
	open file:"R":0 else  quit 0
	kill ^||arcc.txtD 
	use file
	try { 
		for i=1:1 read line set ^||arcc.txtD($i(^||arcc.txtD))=$lb(line) 
	} 
	catch (e) { 
	   close file:"D"
	}
	quit 1
}

How to use it:

select * from arcc.txt where 1=arcc.show('arcc.txt.cls')

And you get:

Class arcc.txt Extends %Persistent [ ClassType = persistent, DdlAllowed, Final, Owner = {_PUBLIC}, ProcedureBlock, SqlRowIdPrivate, SqlTableName = txt ]
{
Property line As %Library.String(MAXLEN = 32000) [ SqlColumnNumber = 2 ];
Parameter SQLTABLETYPE = "GLOBAL TEMPORARY";
Storage Default
{
<Data name="txtDefaultData">
<Value name="1">
<Value>line</Value>
</Value>
</Data>
<DataLocation>^||arcc.txtD</DataLocation>
<DefaultData>txtDefaultData</DefaultData>
<IdLocation>^||arcc.txtD</IdLocation>
<IndexLocation>^||arcc.txt</IndexLocation>
<StreamLocation>^||arcc.txt</StreamLocation>
<Type>%Storage.Persistent</Type>
}
}
 

• Or traditional if you prefer XML output over UDL use 
• $system.OBJ.Export() as export method.

XML might be useful for Global Exports if required

select * from arcc.txt where 1=arcc.showxml('%ZPM.Client.ServerDefD.GBL')

<?xml version="1.0" encoding="UTF-8"?>

And all this is just running over ODBC/JDBC
