dir() with string as argument

[Shankar Iyer (siyer@Princeton.EDU)]

Hi,

Suppose I have a string, sModuleName, that contains the name of a module.  I now want to see what functions are in that module, but if I call dir(sModuleName), I instead get the list of operations that can be done on a string.  Is there any way to convert the string into a format that I could feed to dir to cause the desired effect?  I think I could modify the string a bit and then use the exec command, but I was advised against that on this board last week.
