[kepler-dev] Text File Writer?

[Christopher Brooks]

Use a Constant actor, not a String Constant actor.

Constant will interpret the contents as a variable unless it is inside 
double quotes, in which case it is a string

StringConstant will interpret the contents as a string.

If a Constant actor has the value wrapped in double quotes:
"AString"
then the output will be a string with the value AString

If a Constant actor as the value
AString
The the output will be the value of the parameter named AString

If a StringConstant actor as the value
AString
Then the output will be a string with the value AString.

BTW - for future reference, this is better off sent to Kepler-users than 
Kepler-dev.  The question is about using Kepler, not modifying the Java 
code.  No worries on this.
