Verify Nodes
Verify
nodes test data in a register or file to see if it is a certain type (ASCII,
numeric, or alphabetic). They can also check that the data matches a given
constant, matches the contents of a register, or falls within a given numeric or
alphabetic range.
Usually a
Verify
node Links to one node if the data passes the test and to
another node if it doesn't. For example, a
Verify
node might check to see if the
value scanned is numeric. If it is, the
Verify
node might branch to an
Output
node that sends the value to a file; otherwise, it might display an error message.
