Purpose
Reads data from a file, and stores the data in variables.
Syntax
Input # filenum, var_name [ , var_name... ] filenum is the number of a file opened through the Open File statement.
var_name is the name of a variable.
Description
The Input # statement reads data from a file which was opened in a sequential mode (for example, INPUT mode), and stores the data in one or more MapBasic variables.
The Input # statement reads data (up to the next end-of-line) into the variable(s) indicated by the var_name parameter(s). MapInfo Pro treats commas and end-of-line characters as field delimiters. To read an entire line of text into a single string variable, use Line Input statement.
MapBasic automatically converts the data to the type of the variable(s). When reading data into a string variable, the Input # statement treats a blank line as an empty string. When reading data into a numeric variable, the Input # statement treats a blank line as a zero value.
After issuing an Input # statement, call the EOF() function to determine if MapInfo Pro was able to read the data. If the input was successful, the EOF() function returns FALSE; if the end-of-file was reached before the input was completed, the EOF() function returns TRUE.
For an example of the Input # statement, see the sample program NVIEWS (Named Views).
The following data types are not available with the Input # statement:
- Alias
- Pen
- Brush
- Font
- Symbol
- Object
