creating batch file for NT using dbaccess

Does anybody know any reason why you can't create a batch file to execute several sql statements using dbaccess in windows nt, I am able to run under Unix. The file seems to execute except when I check the tables the changes did not take. It displays an old schema for the database. At the beginning of the script I declare all the informix variables and the at command (cron job) I used the /cmd /c command. Even running the bat file at the command like I get the same results. It only takes the changes if I individual run the dbaccess at the prompt. informix don't support batch files. Do I have to use the command line utilities window instead of the command prompt window ? If I need the command line utilities do you know what exe file that is ? I tried to find any information on options for dbaccess but there seems to be no documentation for it. I am currently using dbaccess -e databasename scriptname. I tried just dbaccess databasename scriptname. system : NT 4.0 with SP3 and Informix OWS 7.22UC1. Thanks
