Issue C63010     [previous patch]

Verbs limited to 256
Submitted by: Brian Rapp     Appeared in: Compilers long ago     Fixed in: -

Using Library 6/11 and either compiler 6.21 or 6.30, verbs greater than 256 have their definitions replaced by something wacky like the effects of "superbrief". This happens even though $MAX_VERBS is set to 500.

Solution (by Andrew Plotkin)

The compiler uses one byte in the dictionary to store the verb number (actually 255-verbnum). Glulx has room for two bytes, but neither the compiler nor the library uses the high byte. At a minimum we should fix the compiler to reject a MAX_VERBS setting higher than 255.
