The TO Record section of the screen has a Reformat column that is used to define the Field Names of fields from the FROM Record that are to be copied to the TO Record.

Reformat

Valid values for this field are:

• The NUM (Relative field number) of a field of the "FROM" record whose value is to be copied. When a relative field number is typed, the field number is translated to a Field Name.
• The Field Name of a field of "FROM" record whose value is to be copied.
• A literal that specifies the value to be copied to the output record. Literals for alpha-numeric fields must be in one of the following formats:

  ='aaaa' where 'aaaa' is the alpha-numeric value.

  =X'xxxx' where 'xxxx' is the hexidecimal value.

• Literals for numeric fields must be in the following format:

  =nnn where 'nnn' is a numeric specification that may contain numeric digits, a decimal place, and a leading minus sign.

• Following are examples of valid literals.

  ='ABC' =1

  =X'FFFFFF' =-33.33

• Fields for which no reformat parameter is specified are set to blanks if alphanumeric and zero if numeric.

Page the sections of the screen for the from and to records either together or separately. To page both the top and bottom sections together, position the cursor in the top three lines of the screen when the forward or backward paging request is made. To page the from or the to section only, position the cursor anywhere within the screen section that you want to page.
