AlphaToInteger Function

Overview

The AlphaToInteger function converts a string containing letter-style numbering (such as those commonly used in spreadsheet columns) to an integer value.

Syntax/Parameters

Syntax

int = AlphaToInteger ( string data );

Parameters

data

A string containing a letter sequence.

Return Value

Returns an int containing the integer equivalent of value or -1 on failure. Use the GetLastError function to retrieve error information.

Remarks

The AlphaToInteger function is particularly useful when parsing data from spreadsheet applications, which commonly denote a column using letter notation or as a “cell address”. The conversion from letters to numbers is zero-inclusive such that ‘A’ becomes 0 and ‘AA’ becomes 26 and so forth. There is no equivalent to negative numbers for alphabetic numbers. Note that the numbering and lettering sequences in XDS and XFR files are incorrect and this routine cannot be used to convert between them.

If the string parameter cannot be converted to an integer, the GetLastError function will return ERROR_SYNTAX.
