RESERVE n LINES.

Effect

If there is not enough space left on the current page for at least n lines, this statement starts a new page. n can be a constant (1,2,3,...) or a variable.

Notes

Before starting a new page, the END-OF-PAGE processing is executed. This differs from NEW-PAGE.

If the RESERVE statement does not trigger a new page, output is continued on the current page.

Use BACK to return to the first line output after RESERVE.

Note

Performance:

The runtime required to execute a RESERVE statement is approx. 1 msn (standardized microseconds).

good

To program page breaks depending on the number of empty lines left on a page, use the RESERVE statement.

To execute a page break on the condition that less than a certain number of lines is left on a page, use the RESERVE statement:

Syntax

RESERVE n LINES.

This statement triggers a page break if less than nfree lines are left on the current list page between the last output and the page footer. n can be a variable. Before starting a new page, the system processes the END-OF-PAGE event. RESERVE only takes effect if output is written to the subsequent page (the system will not generate an empty page).

The RESERVE statement thus defines a block of lines that must be output as a whole. To find out which additional practical effects a block of lines may have, see Specifying a Relative Position.

REPORT demo_list_reserve LINE-SIZE 40 LINE-COUNT 8(2).

END-OF-PAGE.

ULINE.

START-OF-SELECTION.

DO 4 TIMES.

WRITE / sy-index.

ENDDO.

DO 2 TIMES.

WRITE / sy-index.

ENDDO.

RESERVE 3 LINES.

WRITE: / 'LINE 1',

/ 'LINE 2',

/ 'LINE 3'.

thanks
