Orca variables store and retrieve single characters via V, enabling cross-grid wiring

The V operator (variable) both writes and reads single-character values by name. Writing: aV5 stores the value 5 in variable a. Reading: Va outputs the current value of variable a southward. A critical rule: the write must appear above the read on the grid — Orca evaluates top-to-bottom and left-to-right within a frame, so a value written below or to the right of its read location will lag by one frame. Variables allow routing a value from one part of a large grid to another without a physical cable of characters. The K (konkat) operator extends this to read multiple variables at once: 3Kion reads variables i, o, and n side-by-side.

Examples

aV5 → writes 5 to variable a Va → outputs 5 southward 3Kion → reads i, o, n and outputs three characters side-by-side

Assessment

A student writes Va on row 1 and aV5 on row 2. What value does Va output, and why? How would they fix it?
