How to calculate length of array?
Post by Endymion on May 21st, 2012, 1:42pm

Sometimes I need to pass arrays by value, not by reference. So, I want to create tool for cloning arrays. My code not work:

Code:
      def proc_CloneArray(Array#(), return ArrayClone#())
      local ArrayLength% = len(Array#()) *| just idea illustration
      dim ArrayClone#(ArrayLength%)
      ArrayClone#() = Array#()
      endproc

This code works:

Code:
      DEF PROC_CloneArray(Array#(), RETURN ArrayClone#())
      LOCAL ArrayLength%
      ArrayLength% = DIM(Array#(),1)
      DIM ArrayClone#(ArrayLength%)
      ArrayClone#() = Array#()
      ENDPROC

Can I recommend that you don't use the *| style of commenting routinely, since that sort of comment is preserved in a compiled EXE and wastes space:
