I don't see, why it didn't. What is lcDir again?

I just ran this test at command window:

lcDir = '5'
lcTemp = "temp"

store m.lcDir to (m.lcTemp)
?temp
?type('temp')

Worked fine for me.

>Sorry, but your sugestion did not work. However, if you do like this
>store &lcDir to (m.lcString) or store EVALUATE(lcDir) to (m.lcString), it works. Now, there is no macrosubstitution any longer but how to write the code with only name expressions, i.e. without EVALUATE().
