Re: how to check whether the file exists or not ?

Chandru:

Please review the following:

determines if the file, filename, exists. The function returns either a zero
(0) to indicate success or the value returned from the operating system to
indicate an error.

Syntax: stat_var        =       exists(filename)
        filename        =       text literal, column, variable, or expression.
        stat_var        =       decimal, float, or integer variable.

Example:        let #fstatus = exists($filename)

Function arguments are enclosed in parentheses and can be nested.  Arguments
referenced as x, y, and z indicate the first, second, and third argument to
a function.  Otherwise, functions take a single argument.
