Example: Deserialize instruction
The following example shows how the instruction works:
Network 1:
The "MOVE" instruction moves the value "0" to the "#BufferPos" data block tag. The
Deserialize instruction then deserializes the sequential representation of the customer data
from the "Buffer" data block and writes it to the "Target" data block. The Deserialize
instruction calculates the number of bytes that the converted data uses and stores it in the
"#BufferPos" data block tag.
Network 2:
The "Deserialize" instruction deserializes the sequential representation of the data stream
pointed to by "Buffer" and writes the characters to the "#Label" operand. The logic compares
the characters using the comparison instructions "arti" and "Bill". If the comparison for "arti" =
TRUE, the data is article data that is to be deserialized and written to the "Article" data
structure of the "Target" data block. If the comparison for "Bill" = TRUE, the data is billing
data that is to be deserialized and written to the "Bill" data structure of the "Target" data
block.
