I'm trying to use a macro for a datasource name. I've defined it under Administration > Macro Files, and I can use it successfully with other nodes, such as a SQL Query node. In an Expression node, though, it doesn't work. I've tried the two ways the Expression Language Guide suggests:
1) DSN = %%dsn_name%%
2) DSN = "%%dsn_name%%" // with quotes
2) DSN = getvar("dsn_name")
# 1 does not validate
# 2,3 validates, but results in the same error: "Data source name not found and no default driver specified..."
I'm using DM Studio 2.6.

Your expression code will look something like this:
macro1 = getvar("MyMacro")
where MyMacro was defined in a macros file. A few things to check:
