You might try using /bin/ksh -- it gives each function its own argument
list.  Ksh also allows functions to have *local* variables thru the use of
the "typeset" built-in command.

If you are stuck using /bin/sh, you might adopt the convention of always
assigning the function's parameters to uniquely named shell variables --
I typically prefix all variable names with the name of the function (or
an abbreviation) in which they are declared.

For example:

Foo()
{
  Foo_firstArg=$1
  Foo_secondArg=$2

  # possibly call other functions
  # use Foo_firstArg and Foo_secondArg
}
