Syntax:
branchTo (string_expression,... proc_name)Purpose:
branch to the given procedure if the argument types matches the
types given as strings (which may be empty - matching the empty argument list).
The main procedure (pin the example) must be defined without an argument list, andbranchTostatement must be the first statement within
the procedure body.Example:
|  |   proc p1(int i) { "int:",i; }
  proc p21(string s) { "string:",s; }
  proc p22(string s1, string s2) { "two strings:",s1,s2; }
  proc p()
  { branchTo("int",p1);
    branchTo("string","string",p22);
    branchTo("string",p21);
    ERROR("not defined for these argument types");
  }
  p(1);
==> int: 1
  p("hu");
==> string: hu
  p("ha","ha");
==> two strings: ha ha
  p(1,"hu");
==>    ? not defined for these argument types
==>    ? leaving ::p (0)
