backup stored procedures and change parameter names

[Chagh]

hi all,
i've got a problem in restoring my stored procedures. i back up proc table of mysql daabse to back up my SPs. it can easili be restored.

i would like to change name of parameters of my SPs, so i thaught baching them up(dumping them with mysqldump) from mysql db and then changing these parameters using a text editor would solve my problem(there are so many parameter names that should change so i don't want to change them manually by editing the SP)
when i try to restore the changed parameters file with mysql it gives me this error:

"ERROR 1064 (42000) at line 1: You have an error in your SQL syntax; check the ma
nual that corresponds to your MySQL server version for the right syntax to use near 'n++
/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */' at line 1"
(it is not really n++ in the error, these are strange characters instead)

why does this happens? i looked at the sql file but i couldn't see any strange characters and it didn't have changed but the change of name of parameters.

What should i do to change my parameters name in an easy and non-time-consuming way?

Thanks in advance
