The following items are now patched and tested: Multiple labels converging on a single instruction. (Tested in t/op/basic.t) Labels and constants now match the format [a-zA-Z_][a-zA-Z0-9_]* (Tested in t/op/macros.t) P3[7], P3[0x1a], P3[-0b10101], P4[S1], P5["Hello World"] all work. Tests will be added for these fairly soon. -- Jeff <[EMAIL PROTECTED]>
