Re Mathematica 5.2.0.0.
The Module and Block below "should" return the same result, but they don't. The Module's result makes no sense, while the Block's result is what I want.
What's Module doing? The way I read the Help Text, both should return the same result.
Thankx.
Bruce
f[Y_String]:=Module[{x},x=StringReplace[Y,{x_->x}]];
x={"yes","no"};
f@"xyz"
{yes,no}~~{yes,no}~~{yes,no}
f[Y_String]:=Block[{x},x=StringReplace[Y,{x_->x}]];
x={"yes","no"};
f@"xyz"
Out[3]=
xyz
