I tried a lot of things.

When i start quoting i always get messages of command not found. I treid normal single quote ', double quote " and single right quote ` and single left quote ´. Which one should i be using ? Do i have to quote the whole line ? I tried the whole line and parts of the line.

I tried to put the blahblah on the same line .
When i use :

program <> $result 2>&1 << blahblah
the output is coming to my screen

When using spaces between the < < then i get syntax errors near the unexpected token <

Most of the times it keeps waiting for the input. When i enter the string (stays invisible to me) the program starts without problem.
