ABAP Syntax Starting with “F”


Home »ABAP Syntax » ABAP Syntax Starting with “F”


Syntax Starting with “F”

FETCH

Uses a cursor to read entries from a database table.

Syntax

FETCH NEXT CURSOR <c> INTO <target>.

If the cursor <c> is linked with a selection in a database table, FETCH writes the next line of the selection into the flat target area <target>.

FIELD-GROUPS

Declares a field group for an extract dataset.



Syntax


FIELD-GROUPS <fg>.

This statement defines a field group <fg>. Field groups define the line structure of an extract dataset. You can also define a special field group called HEADER: When filling the extract dataset, the system automatically prefixes any other field groups with this field group.

FIELD-SYMBOLS

Declares field symbols.

Syntax

FIELD-SYMBOLS <FS> [<type>|STRUCTURE <s> DEFAULT <wa>].

Field symbols are placeholders or symbolic names for other fields. Pointed brackets are part of the syntax for field symbol names. The <type> addition allows you to specify the type of a field symbol. The STRUCTURE addition forces a structured view of the data objects that you assign to the field symbol.

FIND

Searches for patterns.

Syntax

FIND <p> IN [SECTION OFFSET <off> LENGTH <len> OF] <text>
[IGNORING CASE|RESPECTING CASE]
[IN BYTE MODE|IN CHARACTER MODE]
[MATCH OFFSET <o>] [MATCH LENGTH <l>].

The system searches the field <text> for the pattern <p>. The SECTION OFFSET <off> LENGTH <len> OF addition tells the system to search only from the <off> position in the length <len>. IGNORING CASE or RESPECTING CASE (default) specifies whether the search is to be case-sensitive. In Unicode programs, you must specify whether the statement is a character or byte operation, using the IN BYTE MODE or IN CHARACTER MODE (default) additions. The MATCH OFFSET and MATCH LENGTH additions set the offset of the first occurrence and length of the search string in the fields <p> and <l>.

FORM

Defines a subroutine.

Syntax

FORM <subr> [USING … [VALUE(]<pi>[)] [TYPE <t>|LIKE <f>]… ]
[CHANGING… [VALUE(]<pi>[)] [TYPE <t>|LIKE <f>]… ].

Introduces a subroutine <form>. The USING and CHANGING additions define the subroutine’s parameter interface. The subroutine end with ENDFORM.

FORMAT

Sets formatting options for list output.

Syntax

FORMAT… <optioni> [ON|OFF]…

The formatting options <option i > (such as color) set in the FORMAT statement, apply to all subsequent output until they are turned off using the OFF option.

FREE

Release space in memory.

Syntax

FREE <itab>.

FREE MEMORY ID(<key>).

FREE OBJECT <obj>.

This statement deletes an internal table, a data cluster in ABAP memory, or an external object in OLE2 Automation, depending on the variant of the statement used.

FUNCTION

Defines a function module.

Syntax

FUNCTION <func>.

Introduces the function module <func>. This statement is not entered in the ABAP Editor, but is automatically generated by the Function Builder in the ABAP Workbench. The function module definition ends with the ENDFUNCTION statement

FUNCTION-POOL

Introduces a function group.

Syntax

FUNCTION-POOL.

The first statement in a function group. This statement is not entered in the ABAP Editor, but is automatically generated by the Function Builder in the ABAP Workbench. A function group is an ABAP program that contains function modules.
