ABENDATA_OBJECTS_USAGE_WRITING - DATA OBJECTS USAGE WRITING

Data Objects in Write Positions

Only modifiable data objects, that is, no literals, text symbols, constants, or non-modifiable formal parameters, can be specified as follows at write positions:

• Specification of a visible data object specified at this position using the identifier dobj, a field symbol <fs>, or a dereferenced data reference dref->* if dref is typed completely. Like in read positions, [] can be appended to internal tables to address the table body.

• Specification of a subarea of a flat character-like or byte-like data object using an offset/length specification. An offset or length specification cannot be made in write positions for data objects of the deep data types string and xstring.

• At a declaration position, an inline declaration of a data object or field symbol can be made using a declaration expression.

• Writable expressions can be listed in a result position.

Write-only positions exist, where an operand is overwritten without being read first, and write positions where an operand is read and written.

Notes

• In some write positions, certain expressions can also be specified.

• Enumerated variables can only be used in write positions where the operand type is the enumerated type and only the associated enumerated values can be written.
