11.2.4 Using the CONVERSION Phrase to Display Numeric Data
Use the CONVERSION phrase to convert the value of a numeric data item for
display. It causes the value to appear on the screen as follows:
• In DISPLAY usage
• With a decimal point (if needed) or comma (if DECIMAL-POINT IS COMMA)
• Edited (if needed)
• With a sign (if needed)
Thus, the values of non-DISPLAY data items can be converted to a readable
form. The size of the displayed field is determined by the PICTURE clause of
the displayed item. Example 11–5 and Figure 11–6 show how to display different
types of data with the CONVERSION phrase.
