Subroutine arguments passed in are aliased into the elements of the array @ . GDI uses Bresenham's line drawing algorithm to draw aliased lines. Pipes were supported, and all named resources could be aliased by setting environment variables. Two pointers are said to be aliased if they point to the same location. This form of rendering is also called aliased or "jagged". Some modulation may be seen above the limiting resolution; these may be aliased and phase-reversed. In this case the ID will be aliased to a special tombstone record. In nonregular designs, effects can be fully aliased, partially aliased, or not aliased at all. Both bandlimited (non-aliased) and aliased tones are presented. In this case we say that the samples may be aliased.
