Работаем с Excel через OLE. Нужно воспользоваться методом OpenText. У него есть аргумент типа Array(). Как это дело перевести в синтаксис Clarion'а?

Excel Developer Reference
Workbooks.OpenText Method
Loads and parses a text file as a new workbook with a single sheet that contains the parsed text-file data.
Syntax
expression.OpenText(Filename, Origin, StartRow, DataType, TextQualifier, ConsecutiveDelimiter, Tab, Semicolon, Comma, Space, Other, OtherChar, FieldInfo, TextVisualLayout, DecimalSeparator, ThousandsSeparator, TrailingMinusNumbers, Local)
expression A variable that represents a Workbooks object.
Parameters
Name Required/Optional Data Type Description
Filename Required String Specifies the file name of the text file to be opened and parsed.
Origin Optional Variant Specifies the origin of the text file. Can be one of the following XlPlatform constants: xlMacintosh, xlWindows, or xlMSDOS. Additionally, this could be an integer representing the code page number of the desired code page. For example, "1256" would specify that the encoding of the source text file is Arabic (Windows). If this argument is omitted, the method uses the current setting of the File Origin option in the Text Import Wizard.
StartRow Optional Variant The row number at which to start parsing text. The default value is 1.
DataType Optional Variant Specifies the column format of the data in the file. Can be one of the following XlTextParsingType constants: xlDelimited or xlFixedWidth. If this argument is not specified, Microsoft Excel attempts to determine the column format when it opens the file.
TextQualifier Optional XlTextQualifier Specifies the text qualifier.
ConsecutiveDelimiter Optional Variant True to have consecutive delimiters considered one delimiter. The default is False.
Tab Optional Variant True to have the tab character be the delimiter (DataType must be xlDelimited). The default value is False.
Semicolon Optional Variant True to have the semicolon character be the delimiter (DataType must be xlDelimited). The default value is False.
Comma Optional Variant True to have the comma character be the delimiter (DataType must be xlDelimited). The default value is False.
Space Optional Variant True to have the space character be the delimiter (DataType must be xlDelimited). The default value is False.
Other Optional Variant True to have the character specified by the OtherChar argument be the delimiter (DataType must be xlDelimited). The default value is False.
OtherChar Optional Variant (required if Other is True). Specifies the delimiter character when Other is True. If more than one character is specified, only the first character of the string is used; the remaining characters are ignored.
FieldInfo Optional Variant An array containing parse information for individual columns of data. The interpretation depends on the value of DataType. When the data is delimited, this argument is an array of two-element arrays, with each two-element array specifying the conversion options for a particular column. The first element is the column number (1-based), and the second element is one of the XlColumnDataType constants specifying how the column is parsed.
TextVisualLayout Optional Variant The visual layout of the text.
DecimalSeparator Optional Variant The decimal separator that Microsoft Excel uses when recognizing numbers. The default setting is the system setting.
ThousandsSeparator Optional Variant The thousands separator that Excel uses when recognizing numbers. The default setting is the system setting.
TrailingMinusNumbers Optional Variant Specify True if numbers with a minus character at the end should be treated as negative numbers. If False or omitted, numbers with a minus character at the end are treated as text.
Local Optional Variant Specify True if regional settings of the machine should be used for separators, numbers and data formatting.
Remarks
FieldInfo Parameter Information
You can use xlEMDFormat only if you have installed and selected Taiwanese language support. The xlEMDFormat constant specifies that Taiwanese era dates are being used.
The column specifiers can be in any order. If there's no column specifier for a particular column in the input data, the column is parsed with the General setting.
Notes
If you specify that a column is to be skipped, you must explicitly state the type for all remaining columns or the data will not parse correctly.
If there is a recognizible date in the data, the cell will be formatted as a date in the worksheet even if the setting for the column is General. Additionally, if you specify one of the above date formats for a column and the data does not contain a recognized date, then the cell format in the worksheet will be General.
This example causes the third column to be parsed as MDY (for example, 01/10/1970), the first column to be parsed as text, and the remaining columns in the source data to be parsed with the General setting.
Array(Array(3, 3), Array(1, 2))
If the source data has fixed-width columns, the first element in each two-element array specifies the position of the starting character in the column (as an integer; character 0 (zero) is the first character). The second element in the two-element array specifies the parse option for the column as a number between 0 and 9, as listed in the preceding table.
ThousandsSeparator Parameter Information
The following table shows the results of importing text into Excel for various import settings. Numeric results are displayed in the rightmost column.
System decimal separator System thousands separator Decimal separator value Thousands separator value Text imported Cell value (data type)
Period Comma Comma Period 123.123,45 123,123.45 (numeric)
Period Comma Comma Comma 123.123,45 123.123,45 (text)
Comma Period Period Comma 123,123.45 123,123.45 (numeric)
Period Comma Period Comma 123 123.45 123 123.45 (text)
Period Comma Period Space 123 123.45 123,123.45 (numeric)
Example
This example opens the file Data.txt and uses tab delimiters to parse the text file into a worksheet.
Visual Basic for Applications
Workbooks.OpenText filename:="DATA.TXT", _
dataType:=xlDelimited, tab:=True
Уважаемый Kreator, попытался разобраться в макросе, но FieldInfo еще тянет за собой DataType.kreator писал(а):FieldInfo отвечает за форматирование столбца. T.e. Array(5,2) - означает, что формат пятого столбца - текстовый.
Вроде бы все понятно, Array содержит массивы(2х1) - где первый элемент-номер столбца, а второй-формат. Но даже в макросе не срабатывает Array(1,3).kreator писал(а):Всё просто. Закачиваем огромный текстовый файл в Excel...
