strange function behavior

 

the return in function doesn't work expect: function not return value "return", return information printed in function. it's hard debug when print info in the function when added print, treated part of returned value 

 

function a{

  "333"

  "called"

   return 1

}

 

$b=a

 

 

no output in console when run it

 

function a{

  "333"

  "called"

   return 1

}

 

$b=a

$b

 

$b is

333

called

1

 

 

weird thing, need care it

anything don't 'capture' inside function (assign variable or suppress output) returned function.for more information type in console:

help about_return

 

also, there's excellent blog post mvp keith hill topic:
