STARTINDEX

Purpose:

Sets the starting index for an array in the current SPL function.

Syntax:

STARTINDEX(index)

index

Optional. An integer, the new starting index for array operations. Defaults to the current start index (usually 1).

Returns:

An integer, the previous starting index.

Example:

func1(a)
{
    local i, b;

    startindex(0);
    b = 0;

    for (i = 0; i < length(a); i++)
    {
        b += a[i] * i;
    }

    return(b);
}

This routine sets the starting index for array references to 0, such that the first value of variable a becomes a[0].

Remarks:

STARTINDEX is automatically reset to the configuration parameter SPL_START_INDEX (default 1) when the SPL function exits.

STARTINDEX only effects the current SPL routine, routines called by the current function are not effected.
