Create another string with the correct number of spaces and append that string to st1.

this solution will not help me...

Actually, the number of sapces i have to calulate in the programm, so sometimes 8 space tabs anothertime 20, it depends on code.

Now, i want to change this number of spaces (8,..., 20) as a string (" " or " ") and so on...

thank for each advance..

Of course my suggestion will work:

Write a function that returns a string. Inside the function calculate the number of spaces and build a string that long. Return that string.

Then append the string the function returns to st1.

Calculate the number of spaces. Say, 28. Then run a loop 28 times that appends one space to a newly created string.
