What others have told you should work, unless you got trailing spaces in cAlias name. To avoid this:

lnPeriods=evaluate(forceext(this.cAliasName, alltrim("Periods")))

Forceext() function keeps the trailing or leading blanks in the extension, that's why I trimmed it. If you're running VFP before 6, load FoxTools first.
