Sybase to MSSQL: Getting stored procedure parameters

I started job in new company! This is good news.
Now i will work on Sybase - this is not so good but ok..
Version of db i will use is:
Adaptive Server Enterprise/12.5.0.2/EBF
And this is definitely not good.. its from 2001 :) .. a bit old. 

I'm MS SQL Server fan. As a database developer I really appreciate work done by MS guys in developing SQL server tools: Profiler, Managment studio..
Also some usefull objects are commonly used in my daily work.
Lack of INFORMATION_SCHEMA views was one of first thing I noticed.
And this is my today task: INFORMATION_SCHEMA.PARAMETERS

 CREATE VIEW dbo.INFORMATION_SCHEMA_PARAMETERS  
 AS  
 SELECT db_name() SPECIFIC_CATALOG,  
 user_name(sp.uid) SPECIFIC_SHEMA,  
 sp.name SPECIFIC_NAME,  
 colid ORDINAL_POSITION,  
 param.name PARAMETER_NAME,  
 CASE param.status2 WHEN 2 THEN 'OUT' ELSE 'IN' END PARAMETER_MODE,  
 t.name AS DATA_TYPE,  
 t.length LENGTH  
 FROM dbo.sysobjects AS sp  
 INNER JOIN syscolumns AS param ON (param.number = 1) AND (param.id=sp.id)  
 LEFT JOIN systypes AS t ON t.usertype = param.usertype  
 GO 

 CREATE VIEW INFORMATION_SCHEMA_TABLES  
 AS  
 SELECT  
 db_name() AS TABLE_CATALOG,  
 user_name(uid) AS TABLE_SCHEMA,  
 o.name AS TABLE_NAME,  
 CASE o.type  
 WHEN 'U' THEN 'BASE TABLE'  
 WHEN 'V' THEN 'VIEW'  
 END AS TABLE_TYPE  
 FROM sysobjects o  
 WHERE o.type IN ('U', 'V')  
 GO 

 CREATE VIEW INFORMATION_SCHEMA_COLUMNS  
 AS  
 SELECT db_name() TABLE_CATALOG,  
 user_name(o.uid) TABLE_SHEMA,  
 o.name TABLE_NAME,  
 c.name COLUMN_NAME,  
 colid ORDINAL_POSITION,  
 t.name AS DATA_TYPE,  
 t.length LENGTH,  
 CASE WHEN allownulls = 1 THEN 'YES' ELSE 'NO' END IS_NULLABLE  
 FROM dbo.sysobjects AS o  
 INNER JOIN syscolumns AS c ON (c.number = 0) AND (c.id=o.id)  
 LEFT JOIN systypes AS t ON t.usertype = c.usertype  
 GO  

As you can see my version of INFORMATION_SCHEMA_PARAMETERS is pretty simpler than the MS version, but most impotent things are in ..
