Function

Changes several values at the same time (always in connection with structures).

Declaration

Parameters

Description

The structure types of the parameters dstIdent_Rec and srcIdent_Rec must be always identical (otherwise the action generates the error _ERR_RECORD_NO_COMP). The same applies to their size. Their type may be:

• RECORD,

• ALIAS (typed),

• An object of the Structured variable type.

The action sets the values of items from srcIdent_Rec to the values of items from dstIdent_Rec. If dstIdent_Rec is the reference to a row, then srcIdent_Rec must be the reference to a row, too. Accordingly if dstIdent_Rec is a reference to a whole value, then srcIdent_Rec must be a reference to a whole value, too.

Therefore, the combination:

RECORD (SD.RecordDef) _lArr1

SET _lArr1[1] WITH SV.Structure

is not permitted and the script editor reports an error during the compilation.

When setting a whole value, the number of rows must be identical. For example:

RECORD (SD.RecordDef) _lArr1

SET _lArr1 WITH SV.Structure

The action SET WITH will generate the error _ERR_RANGE_ERROR (the size of SV.Structure is 10 rows and the size of the local variable _lArr1 after the declaration is just 1 row). Correct copying the whole value into the local variable is as follows:

RECORD (SD.RecordDef) _lArr1

REDIM _lArr1[SV.Structure\DIM]

SET _lArr1 WITH SV.Structure

When copying values to a local variable of RECORD type, which contains items of Object type, the action sets values of the objects, the individual adjusted items are pointed to. This effect is not always desirable. Therefore it is possible to use the NOALIAS modifier when you declare a local variable of RECORD type as follows:

RECORD NOALIAS (SD.RecordDef) _lArr1

For a local variable declared in this way, the pointing feature for all items of Object type is disabled. Their type is not predefined. A value of any type may be assigned to them. For example:

_lArr1[1]^Object := 1

_lArr1[1]^Object := "Text"

Example

RECORD (SD.RecordDef) _lArr1
RECORD (SD.RecordDef) _lArr2

INT _index

REDIM _lArr1[5]
REDIM _lArr2[5]
;... initialization of values to the local variable lArr1

; copying values of the 3rd row from _lArr1 into the 2nd row of _lArr2
SET _lArr2[2] WITH _lArr1[3]
; copying the whole value using a loop
; it assumes the same array sizes 
_index := 1
NextRow:
IF _index <= _lArr1\DIM THEN
SET _lArr2[_index] WITH _lArr1[_index]
_index := _index + 1
GOTO NextRow
ENDIF ; The same result may be achieved by using SET WITH action
SET _lArr2 WITH _lArr1
