How to add text to a text file

[Mansour Ayouni]

Hello All,

To read text from a temp.txt file we can say:

cContent = read("temp.txt")

And we have all the text contained in the file in the cContent variable.

To add text to the file, we use:

write("temp.txt", "my new text goes here").

The problem with this last syntax, is that the old content of the file is removed. Only "my new text goes here" is there...

My question is: how can I add new text to an existing text file without deleting its current content?

Best,

Mansour

Hello Mansour,

hFile = fopen("temp.txt","a+")

cContent = fread(hFile,unsigned(1,15,"<<"))

fwrite(hFile,"my new text goes here");

fclose(hFile)

We use append plus (a+) to open a stream at the beginning of the file because you are reading from it first, otherwise we use only append (a) to concatenate, e.g. if we read nothing.

Thanks a lot Ilir!

All the best,

Mansour
