string variable used in path reference

[eviewsnew]

I'm trying to use a string variable to indicate the directory path for opening a file. But it doesn't work. But if i specify the whole path clearly and without the string variable, it works.

Can you help?

Is there any good reference book for Eviews programming for beginner?

thanks!

works:wfopen \\sac-psas-01\econ\riskindex\RI_V3.1\data\2011Q1\ur_nsa_eviews.csv

doesn't work:

%dir="2011Q1"
wfopen \\sac-psas-01\econ\riskindex\RI_V3.1\data\%dir\ur_nsa_eviews.csv

Try:

Code: Select all

%dir="2011Q1" wfopen \\sac-psas-01\econ\riskindex\RI_V3.1\data\{%dir}\ur_nsa_eviews.csv
