| Hi:
| I want to use local assignment done for a 
subscripted variable, where
| x1 is ought to be read as x subscript 1, and 
evaluate at local values
| function g[x1] and use the result later on. My 
code (not actual, just
| an example) is as follows:
| x1=0;
| With[{x1=1},y=g[x1]] (* is some specific 
arbitrary function, say x1^2
| *)
| y
| My error message is "Local variable 
specification {x1=0} contains x1=0
| which is an assignment to x1; only assignments 
to symbols are allowed"
| Where on earth does Mathematica see a function 
in x1. To me this is
| just a symbol. Please advise on a workaround.
