**''TOP =''** ''[[integer|<Integer>]]'' **'';''**\\
**''Y = ;''**\\
**''Y0 = ;''**\\


The upper position of the screen area of a **''$SECTION''**, **''$GROUP''** or **''$SCENE''** command. If this parameter is specified, Traffic checks that the required area of the screen/parent section is free; when it is not, the Movement is delayed until it becomes free. If this parameter is missing, Traffic selects a random position the Movement fits.
