问题
Various EDI definition documents have tables with the following headers:
SEGMENT, DATA ELEMENT, M/C, F/V, PICTURE, REMARKS
I have two questions: 1. PICTURE appears to define the required format, is the term picture a reference to a specific formatting language type?
2.What does F/V stand for?
See the following for examples of this data table:
