RUNWAYS (Any Size) - ------- No markings, no lighting = 58 Bytes All markings, all lighting = 58 Bytes H. NAVAIDS - ------- NDB = 20 Bytes VOR = 20 ILS = 24 FAN = 14 (Inner, Middle, and Outer Markers) I. TIMING GATES (Any Size) - ------------ All Gates = 57 Bytes NOTES ----- A. Roads. Unless you need the white borders on a divided highway it uses less memory to substitute 2 parallel city streets, which are the same width (52'). You will save 23 bytes by using one road with a "Skip" instead of 2 roads. Therefore you can save 207 bytes by using one road with 9 "Skips" instead of 10 roads. You can even change colors and types of road when you skip. The saving is still 23 bytes per hop, skip or jump. B. Rivers. The saving on "Skips" is the same as for roads. C. Buildings. Multi-colored buildings use no more memory than plain ones. All multi- sided buildings use 46 bytes, regardless of the number of sides and type of roof. D. Mountains. As you can see, each additional side adds 23 bytes. Each additional peak adds 38. Height does not seem to affect memory requirements. Likewise the number of colors used for faces. You do no need to hit "P" for the last point on the base of a mountain. If you are using a mouse, inadvertant slight movement after hitting "P" can cause you to get charged for an extra side. E. Lines. The saving per "Skip" is 23, the same as for Rivers and Roads. F. Polygons. Size does not seem to be a factor affecting memory usage. However you should note that a 3-sided Poly uses more than a 4-sided one. Therefore if you are drawing triangular polys put an extra point in one of the sides and save 12 bytes. G. Runways. You cannot save anything here. A 2-mile runway with all the options is a bargain at 58 bytes, the same as a plain half mile strip. John A. Kelley, 73670,3107 July 9th., 1992.
