Write a G$-$code sequence that will position the tool of a machine. Let the range be from $-200$ to

$+200$ mm and do five bidirectional positioning runs. Move along a line in forward and reverse

fashion positioning every $50mm.$ At each location wait $7$ seconds before moving to the next

position. At each end of travel move an additional $2mm$ before returning to the end point so

that each forward or reverse direction approaches from the same direction. At the end of $1^{st}$ line

of code before the semicolon $($Also known as End of Block$)$ put in a F$1000$ command which tells

the machine to move at $1000m\frac{m}{i}n$ch $($metric programming$).$
