Outputs the field f in the correct format for its type to the current list. The field f can be:
TABLES SPFLI. DATA N TYPE I VALUE 123. ... WRITE N. WRITE SPFLI-FLTIME. FIELD-SYMBOLS <CF>. ASSIGN 'NEW YORK' TO <CF>. WRITE <CF>. WRITE: '---->', SPFLI-DISTANCE. WRITE: TEXT-001, SPFLI-ARRTIME.
WRITE: 'Time:'(001), SPFLI-ARRTIME.
Text symbols can be addressed in two different ways (TEXT-001 or 'Time:'(001)).
If no explicit position is specified for a field on a new line,
it is output on the left (in column 1). Otherwise, output is one
column removed from the previously output field. If a field does
not fit on one line, a new line is started.
You can perform explicit positioning with a position and length specification (see addition 1) or with ABAP/4 statements (e.g. POSITION ). In this case, the field is always output at the defined position, even if the line is not quite long enough for it to fit completely.
If a field is too long to fit completely on the line, the excess characters are truncated.
Each field occupies a number of characters in the list. If this
number is not explicitly defined (see addition 1), the system uses
a type-specific standard length or the output length specified in
the ABAP/4 Dictionary.
Type-specific output: (len = field length)
|Type||Standard output length||Output|
Numeric fields (types P, I and F) are always output right-justified, but all other types are left-justified; if required, blanks are used for padding. With numeric fields, leading zeros are replaced by blanks. If there is enough space, types P and I have thousands separators. To accommodate the decimal point, the output length of type P fields is 1 byte longer.
System fields that are useful when generating lists are documented in System Fields for Lists.
WRITE AT f (position and length specification before the field)
You can use the position and length specification f to define
the precise output position and length of a field. The
specification consists of:
/ New line
p Output position (1-3 character number or variable)
(l) Output length (1-3 character number or variable)
Combinations are possible.
DATA: WORD(16), VALUE '0123456789ABCDEF', COL TYPE I VALUE 5, LEN TYPE I VALUE 10. WRITE AT / WORD. "new line WRITE AT 5 WORD. "column 5 WRITE AT (10) WORD. "output length 10 WRITE AT /5(10) WORD. "new line, column 5, length 10 WRITE AT COL WORD. "column = contents of COL WRITE AT (LEN) WORD. "output length = contents of LEN WRITE AT /COL(LEN) WORD. "new line, column = contents of COL "output length = contents of LEN
The position and length specification must appear before the field.
You can modify the output of the field f by using one of the special formatting options.
Outputs the field with the specified output formats (color,
intensity, ready for input, ...).
You can use the same output options as for FORMAT. If no specifications are made, the field is output with the standard formats or with the format set by a preceding FORMAT statement.
DATA F. FORMAT INTENSIFIED OFF INPUT. WRITE F INPUT OFF INVERSE COLOR 3.
The format specifications with WRITE apply only for output of the field f. They modify the currently valid format for this field. This means that, in the above example, the non-highlighted output remains for the field F. When f has been output, the system reverts to the old format.
When you output a list, this is sometimes combined with vertical and horizontal lines to form closed boxes:
