=> R0 = pointer to 4-word data structure (not 0)
R1 = pointer to token (possibly wildcarded)
R2 = pointer to buffer for result
R3 = size of buffer
R4 = index (0 for first time)
<= R0, R1 preserved
R2 = 0 if no more matching tokens, else preserved
R3 = length of result excluding terminator
R4 = next index
This SWI looks up tokens that match the given wildcarded token specification. The token returned in the buffer has the same terminator as the wildcard in R1.
See PRM 3, page 751.
