Host command from sqlplus based on a condition

Question

I am on an Oracle 10.2.0.3.0 database running on sun solaris.
Am using my sqlplusw on my windows xp professional to do the below :
SQL> select * from v$version;
BANNER
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bi
PL/SQL Release 10.2.0.3.0 - Production
CORE 10.2.0.3.0 Production
TNS for Solaris: Version 10.2.0.3.0 - Production
NLSRTL Version 10.2.0.3.0 - Production
I have 4 variables declared in sqlplus for which I get my values from anonymous pl/sql blocks :
print db1_status;
DB1_STATUS
3
print db2_status;
DB2_STATUS
0
print db3_status;
DB3_STATUS
1
print db4_status;
DB4_STATUS
0
I needed some help with doing this :
Based on the values of each these variables, I wanted to invoke the host command to run stuff like
if db1_status = 3 then
host ...something
if db2_status = 0 then
host ...something
I am looking for a way to do this without creating an external procedure or java stored programs. Are there any?
Thanks

Need to use a batch file (.bat) to utilize SQL Plus while generating the SQL statements within the .bat file.
Example:
Inside SQL Plus
SQL> create table testme (name varchar2(255), value number(5));
Table created.
SQL> insert into testme(name, value) values ('db1_status', 3);
1 row created.
SQL> insert into testme(name, value) values ('db2_status', 0);
1 row created.Create a .bat file (Using test.bat)
test.bat
@echo off
echo select value from testme where name = 'db1_status';>temp.sql
echo exit >> temp.sql
sqlplus -S %2/%3@%1 @temp.sql > result.dat
for /f %%x in ('more result.dat') do set RESULT=%%x
if "%RESULT%" == "3" goto :DB1_STATUS_3
if not "%RESULT%" == "3" goto :DB1_STATUS_NOT_3
goto :EOF
:DB1_STATUS_3
echo db1_status = 3
**ENTER SYS COMMANDS HERE**
goto :EOF
:DB1_STATUS_NOT_3
echo db1_status != 3
**ENTER SYS COMMANDS HERE**
goto :EOF
echo select value from testme where name = 'db2_status';>temp.sql
echo exit >> temp.sql
sqlplus -S %2/%3@%1 @temp.sql > result.dat
for /f %%x in ('more result.dat') do set RESULT=%%x
if "%RESULT%" == "0" goto :DB2_STATUS_0
if not "%RESULT%" == "0" goto :DB2_STATUS_NOT_0
goto :EOF
:DB2_STATUS_0
echo db2_status = 0
**ENTER SYS COMMANDS HERE**
goto :EOF
:DB2_STATUS_NOT_0
echo db2_status != 0
**ENTER SYS COMMANDS HERE**
goto :EOF
:EOF
del temp.sql
del result.dat
@echo onAs you can see, this is a simple if/then which takes the value from a dynamically created SQL file (temp.sql) and uses it do determine the next system commands to execute.
Hope this is what ya needed.
