- use myvar1 and myvar2, without the "$";
- put a space between the variables:

$ echo "blah" | awk 'BEGIN {myvar1=0}
{myvar2=1;system("echo "myvar1" "myvar2)}'
0 1

All the commands are tested with bash and GNU tools, so they may use
nonstandard features. I try to mention when something is nonstandard (if
I'm aware of that), but I may miss something. Corrections are welcome.
