Field symbols

What are field symbols ? where u will use it?

HI,

Field symbols are used to dynamically assign a variable value.

Like:

FIELD-SYMBOLS: <FS> TYPE ANY.

data: A(10) type c.

A = 'ddd'.

Assign A to <FS>.

Hi,

Field symbols offer functionlity similar to pointers in other programming languages. It does not occupy memory for the data object, it points to the object that has been assigned to the field symbol. You use the assign command to relate to the data object. After the assign operation you can work with field symbol in the same way as with the object itself.

You define the field symbol as: field-symbols <fs>.

Consider this:

field-symbol <fs>.

data field value 'X'.

asssign field to <fs>.

The field symbol <fs> now inherits all the properties from the assigned field, and you can work with the field symbol in the same way as with the field itself.

Take a look at the examples given here for working with field symbols:

Simple program.

data : letter(10) .

field-symbols : <fs> type any.

assign letter to <fs> type 'X'.

write <fs>.

Simple program.

TYPES: BEGIN OF NAME,

NEXTNAME(10),

FIRSTNAME(10),

LASTNAME(10),

END OF NAME.

FIELD-SYMBOLS <F> TYPE NAME.

DATA: LINE(30).

LINE = 'JOHN SMITH SHRI'.

ASSIGN LINE TO <F> CASTING.

WRITE: / 'Lastname:', <F>-LASTNAME,

'Firstname:', <F>-FIRSTNAME,

'Nextname :', <F>-NEXTNAME.
