Different hardware platforms and operating systems use different standards to represent data. Some use ASCII (American National Standard Code for Information Interchange); some use EBCDIC (Extended Binary-coded Decimal InterChange). Each can use different binary patterns to represent data. Some use a single hexadecimal byte to represent their characters; others might use more. Each has its own way of storing numeric data.
When TXSeries for Multiplatforms communicates with other systems and data flows from one system to another, that data might need to be converted from one format to another.
