Processing ASCII characters Chapter 2
You can extract and convert a value from an ASCII message that contains
multiple values. A message may look like the following example:
Rung A: Find and Convert a
Floating-Point Value
The FIND instruction locates characters within a string.
• The Source contains the string tag to search.
• The Result contains the location where the FIND instruction locates the
search value you specify.
The MID instruction identifies a group of characters within a string and places
them in their own string tag.
