Input #
 
Reads a list of values from a text file

Syntax

Input # filenum, variable_list

Parameters

filenum
a file number bound to a file or device
variable_list
a list of variables used to hold the values read

Description

Reads from a text file through a bound file number a delimiter-separed set of values and writes them in reading order into the variables in variable_list. If a variable is numeric the read value is converted from its string representation into the corresponding type.

Numeric values are converted similar to the procedures Val and ValLng, using the most appropriate function for the number format.

Delimiters may be commas or line breaks. (Whitespace is also treated as a separator after numbers.) . A string including a comma or a whitespace must be surronded by double quotes.

To read an entire line into a string, use Line Input instead .
Write # can be used to create a file readable with Input #.

Example

Dim a As Integer
Dim b As String
Dim c As Single

Open "myfile.txt" For Output As #1

Close #1

Open "myfile.txt" For Input As #1
Input #1, a, b, c
