      Hello all!
      I use Autoit for a while, already made some automation for a TV station's master control room with it. I made a UDF to easily work with PAL timecode and time with milliseconds, convert, add or subtract them. Feel free to use it if you want something like this

      hi everyone!
      I need some help with my rpn calculator.
      I first translated it from vbscript to autoitscript and that's when i stumbled on problem one:
      (46) : ==> Array variable has incorrect number of subscripts or subscript dimension range exceeded.:
      $Stack[ubound($Stack)] = $Item
      ^ ERROR
      After that (and i know this from testing it as a vbscript) it can't work with negative numbers:
      "1 - - 2" to Reverse Polish notation = "1 - 2 -" gives me the build in error...
       
      Can you guy's help me with my code pleas?

      I initially created this to improve my C# understanding and what a learning curve it was. So I decided to directly translate the C# source code I had into AutoIt as a way of showing off the >Stack UDF (which you will need). Of course it can be changed not to use the Stack UDF, but why reinvent the wheel and make life even more difficult.
