Line Input#
Reads the data of one line from the file.
Format
Line Input #<fileNo>, <data>
Parameter
Return value
None.
Description
Read the data of one line separated by the line break code from the file of the file number specified in the
<fileNo> parameter. The Input# function operates in similar way. This Line Input# function reads all data
within a single line as a character string type data, whereas the Input# function reads multiple data within a
single line and data type specifications for each piece of read data are required in advance.
Specify the variable to store the read data in the <data> parameter.
When a read line only has a line break code, a null character string is stored in the read data.
If the read data contains a double quoted character string, the double quotation marks (") are also read as
characters.
If an unopened file number is specified in the <fileNo> parameter, an "Illegal function call" error will occur.
If a file number of the opened file by a macro function other than the Open For Input As# function is specified
in the <fileNo> parameter, an "Illegal function call" error will occur.
If a value outside the range of 0 to 15 is specified in the <fileNo> parameter, an "Illegal function call" error will
occur.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a value outside the range -2147483648 to 2147483647 is specified as an integer parameter, an "Overflow"
error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
