I am using the ASCII Controll Sequences to move the cursor on the screen (my site does not have Term::ANSIScreen installed and so I must make do with what we have). The way it works is like this. 
print ("\033[2;5H");

Which would position the cursor to down 2 rows and over 5 columns from top left. I can use variables by doing the following 
$columns = 5;
print ("\033[2;${columns}H");

But my problem comes from when I want to increment the variable without using an intermediate step. Such as; 
$a = 5;
print ("\033[3;${a}HStart Here $a");
print ("\033[4;${$a+=10}HEnd Here $a\n");

[download]
What prints out is 
    Start Here 4
End Here 14

So Perl is updating $a, but it doesn't seem to be passing it to the Escape Sequence. Since "End" starts against the wall that means it getting no value. I know I can do $a+=10; inbetween the print statements, but I was wondering if I can shorthand it even more.
