Conversion of batch file parameter to varchar2

Question

Hello, I currently have a batch file that accepts a parameter: login/password@database.
The way i assign it in the batch file is as follows:
%1 parameter login/password@database
The batch file then calls sqlplus to run a script, called test.sql, it passes the %1 parameter to the test.sql script. The call from the batch file looks as follows:
sqlplus %1 <test.sql> %1
where test.sql is the location of the script.
The problem arises when i try to assign the %1 parameter which is equal to say, johndoe/doe@database, to a varchar2 variable in the pl/sql anonymous block.
Here is how that assignment looks:
declare
login varchar2(50);
begin
login := %1;
end;
The error i recieve is:
invalid indentifer 'johndoe' must be declared.
I was thinking to solve this problem all i need to do is change it to a character datatype, however, when i try TO_CHAR or using concatenation using the '||' operator
they do not work.
Does anyone have any ideas<QUESTION MARK>
Thanks.
