Hi All,

How do I create a parameter from my brainscript? I would like to use part of my graph parameter as my filename. How do I manipulate it using brainscript then incorporate it into the filename? Filename only seems to take parameter values not variable created with brainscript.

Below is a sample of what I like to do.

Graph Parameter: BeginDate = 2010-01-01

Script: ThisMonth= {{^BeginDate^}}.month()

Output Delimited Node: File = {{^ThisMonth^}}.txt

Thank-you.

Edith,

I refer you to this thread...

It helped me do the same thing. Instead of using data from a file you can use a static data node with one field with the value of the parameter:

eg;

Field:String
{{^dateParameter^}}

Cheers

You have it almost right. Parameters are always just textual substitution, so you want to do this:

"{{^BeginDate^}}".toDate("CCYY-MM-DD").month() to get a month value from date parameter.

And then, as the other thread shows, you can use the parameter formed to do a move from a hardcoded name to the desired name.

Unfortunately, you can't currently provide BRAINscript for the file parameter to an output delimited node. You could include the parameter fully though, as in:

c:/some/path/OutputFile_{{^BeginDate^}}.txt in the Output Delimited Node,

and if that is good enough, you are all set, but if you need to, you could then follow it by a node that does a move, using moveFile in BRAINscript, creating the name using the format shown above to extract the month.

Let us know if you need an example.

Cheers

For an example of how to use moveFile, look at link Mick has earlier. After creating the file, you execute a filter node that contains moveFile to give the file the desired final name. Here is the link again: http://community.mda-data.com/showthread.php?t=39
