I've pasted the code I'm working with to the bottom of this question.

I need some help setting some variables in the attached script.  I don't know anything about TSQL  SQL Server generated the code for me.  I use the code to set up jobs for the new databases we create.  Currently I do a search and replace to change the variables its sort of tedious.   I would prefer, if possible, to be able to change a couple parameters at the very beginning of the script and have them flow down to the body of the script.  

In the example script the text "AHEF_SV6" (the database name) and "AEHF_SV6_Friday" (the name and description of the job) are two pieces of text I woul like to set at the beginning of the script.

Also in the script below:
Can the line " @active_start_date = 20100617 " be changed to always have the current date?  So I don't have to remember to change it.

Can the line " @freq_type = 8 " be changed so I can set the day number (8) at the begining of the script?  This would help me to not forget to set it and not accidently screw up the body of the text.

Thank you for your time.
