FetchValue function

Syntax

FetchValue(scrollpath, target_row, [recordname.]fieldname)

where scrollpath is:

[RECORD.level1_recname, level1_row, [RECORD.level2_recname, level2_row, ]] RECORD.target_recname

To prevent ambiguous references, you can also use SCROLL.scrollname, where scrollname is the same as the scroll level’s primary record name.

Description

Use the FetchValue function to return the value of a buffer field in a specific row of a scroll level.

Note:

This function remains for backward compatibility only. Use the Value field class property instead.

This function is generally used to retrieve the values of buffer fields outside the current context; if a buffer field is in the current context, you can reference it directly using a [recordname.]fieldname expression.

Parameters

Parameter	Description
scrollpath	A construction that specifies a scroll level in the component buffer.
target_row	An integer specifying the row on the target scroll level where the referenced buffer field is located.
[recordname.]fieldname	The name of the field where the value to fetch is located. The field can be on scroll level one, two, or three of the active page. The recordname prefix is required if the call to FetchValue is not on the record definition recordname.

Returns

Returns the field value as an Any data type.

Example

The following example retrieves the value from field DEPEND_ID in record DEPEND on row &ROW_CNT from scroll level one:

&VAL = FetchValue(SCROLL.DEPEND, &ROW_CNT, DEPEND.DEPEND_ID);
