How do i replace a string in text file in loop?
显示 更早的评论
I need to replace a text in a notepad in loop. In the below attached file(input), the term 'zout' needs to be replace from 'zout = 0, 0.25' to 'zout = 0.25, 0.50'(and execute a bunch of other commands inside the loop) until 'zout= 28, 30'.I have attached the code(SBDRUN1) used for running the input file below.
Thanks in advance

You can create a new string with sprintf:
zout = sprintf('zout = %d, %d\n',var1, var2);
If this line is inside the a for loop then it will update the string with new variables each iterations. This can then be printed into the file with fprintf or a similar command.

Unless you are using ActiveX, you can't replace text inside a file. What you can do is read the file, make the changes you want, and then writing the result to the text file, replacing it in its entirety.
