Shared job limit in BTEQ script

Hi,

Can we set a limit on BTEQ script to not to run the script when  its running state,we have one bteq script thats running dialy with different params  , but some times when two instances of script runs then its getting conflict and tables are getting locked, is there any way in Bteq to have a limit that if one instance of script running then another instance should wait.
