AFIND Search Example
In the following example, the AFIND instruction is used to search for the “day” portion
of “Friday” in the ASCII string “Today is Friday.”, which had previously been loaded into
V–memory. Note that a Search Starting Index of constant (K) 5 combined with a Forward
Direction Search is used to prevent finding the “day” portion of the word “Today”. The Found
Index will be placed into V4000.
