How to read in a text or CSV file?
Two methods can be used to read a text or CSV file: Method 1: Using the fReadLine function Principle To read a line in a text or CSV file: - Open the file with fOpen.
- Read the line with fReadLine.
- Close the file with fClose.
Code samples - Reading a line:
// Read a simple string
nFileNum is int
sLineRead is string
nFileNum = fOpen ("MyFile.txt", foRead)
IF nFileNum <> -1 THEN
// Read the line
sLineRead = fReadLine(nFileNum)
fClose(nFileNum)
END
- Reading a data file in TXT format (import)
nFileNum is int
sLineRead is string
nFileNum = fOpen ("ImportProducts.txt", foRead)
IF nFileNum <> -1 THEN
sLineRead = fReadLine(nFileNum) // Read the 1st line
WHILE sLineRead <> EOT // Check the end of file
// Process the line
...
// Read the next line
sLineRead = fReadLine(nFileNum)
END
fClose(nFileNum)
END
Method 2: Using the fLoadText function Principle To read a text or CSV file in a single operation: - Declare a string variable.
- Load the entire file content in memory in this variable with fLoadText.
- Process the string in memory to analyze its content.
Code example // Read a data file in TXT (import)
sFileContent is string
sLine is string
// Load the file content in memory
sFileContent = fLoadText("ImportProducts.txt")
FOR EACH STRING sLine OF sFileContent SEPARATED BY CR
// Process the line
...
