IMSADF II (Information Management System Application Development Facility Version 2) is an application generator which runs under IMS. As an application program, it can automatically read data from a screen, manipulate the data, perform data base updates, and write the screen back to IMS, as well as perform various other data processing functions. In previous versions of IMSADF, there was no capability to process a field in variable character (VARCHAR) format. VARCHAR fields begin with a two-byte binary length followed by up to 253 bytes of character data. The two-byte binary length determines how many bytes of the following character data constitute the field value.
