First, you probably would be better off with an array, rather than 100
variables with numeric postfixes. You can use push!() for this.
Second, the error is because Julia is trying to parse the left hand side as
an attempt to define a function, using the shortened f(x) = y function
definition syntax. Here, f is *, and the literal `"m" * string(i)` is being
interpreted as the name of its argument, but this is not a valid identifier.
Finally, although you almost certainly don't want to do what you're trying
to do, you can if you separate creation of the symbol from evaluation:
var_name = symbol("m" * string(i))
@eval $var_name = readcsv(string("m", i, ".txt"))
