How To Run All Scripts Present In A Folder

My directory has around 100 sql files to run via sqlplus. For test purpose, I took only 2.I tried following code in the batch file to process those 2 files:

for /f %%a IN ('dir /b *.sql') do ( sqlplus -S sys/ankit@orcl2 as sysdba @%%a )But as the following output shows, only 1 was processed :

C:\Documents and Settings\Administrator\Desktop>cd C:\temp\Copy_WMGIS_DWH\6DBlinks\
C:\temp\Copy_WMGIS_DWH\6DBlinks>for /F %a IN ('dir /b *.sql') do (sqlplus -S sys/ankit@orcl2 as sysdba @%a )
C:\temp\Copy_WMGIS_DWH\6DBlinks>(sqlplus -S sys/ankit@orcl2 as sysdba @PUBLIC.MAXIMO.sql )
Database link dropped.
Database link created.

It stops after this. But when I press ctrl+C , it asks me if to stop (Y/N). I choose 'N', it runs second file as shown below:

Terminate batch job (Y/N)? n
C:\temp\Copy_WMGIS_DWH\6DBlinks>(sqlplus -S sys/ankit@orcl2 as sysdba @PUBLIC.VENTYX.sql )
Database link dropped.
Database link created.

It should run second one itself, not via user interaction.
