ADD - THEN, UNTIL
Obsolete Syntax
ADD { { dobj1 THEN dobj2 UNTIL dobj
{ {TO result} | {GIVING result [ACCORDING TO sel]} } }
| { dobj FROM pos1 TO pos GIVING result } }
[RANGE range].
Effect
This variant of the statement ADD, which is not allowed in classes, adds strings of data objects that are stored in equal distances from one another in the memory.
In both variants, an unhandleable exception is raised if addresses are accessed that do not contain suitable data objects.
All data objects of the string must be within a structure. If this cannot be detected statically in the syntax check, a structure range with the addition RANGE must be specified. If the data objects of the string are not part of the specified structure when the statement is executed, an unhandleable exception is raised.
Note
The function of these variants of the ADD statement depends on the structure of the working memory. Memory-based operations of this type should be avoided. They are not allowed in classes and can be replaced as required by the statement ASSIGN with the addition INCREMENT.
Example
The components of the structure numbers specified on the selection screen are added and the total is assigned to variable sum.
DATA: BEGIN OF numbers,
one TYPE p LENGTH 8 DECIMALS 0 VALUE 10,
two TYPE p LENGTH 8 DECIMALS 0 VALUE 20,
three TYPE p LENGTH 8 DECIMALS 0 VALUE 30,
four TYPE p LENGTH 8 DECIMALS 0 VALUE 40,
five TYPE p LENGTH 8 DECIMALS 0 VALUE 50,
END OF numbers,
sum TYPE i.
