Syntax

<Result> = HGetCurrentPosition([<Data file> [, <Item>] [, <Precision>]])

<Result>: Integer

Approximate current position, plotted to the [1;1000] interval.
-1 if an error occurs (empty data file, filter returning no result, etc.). HErrorInfo returns more details about the problem.

<Data file>: Optional character string (with or without quotes)

Name of data file used. If this name is not specified, HGetCurrentPosition will use the last data file used by the last HFSQL management function (function starting with "H").

<Item>: Optional character string (with or without quotes)

Name of item used. If this name is not specified, HGetCurrentPosition will use the last item used by the last HFSQL management function (starting with "H").

<Precision>: Optional integer

Defines the precision with which the position is evaluated. Caution: The higher the precision, the longer it takes to evaluate the position in the file.
hPrecisionLow Low precision.
hPrecisionMedium
(default value) Medium precision.
hPrecisionHigh High precision.

This parameter is ignored.
This parameter is ignored. The calculation is always performed with a high precision.

Remarks

Position in relation to a key item or to a non-key item

For a key item, the position returned is relative to the position of the record in the index of this item.

For a non-key item, the position returned is relative to the record number in the data file (see HRecNum).

Position in a filtered browse

If a filter with bounds is defined (HFilter without condition string but with lower and upper bounds), the returned position is relative to the records selected by the filter.

If a condition string is given to HFilter, the returned position ignores the filter.
