Hello,
Are those lines at the begining of the file?

Dear all; Many thanks for your useful comments and codes.
I tried both Rui's and Jim's codes.
Jim's codes gave an error as below:
"Error in substr(inputline, 1, begincol3 - 1) :
object 'inputline' not found"
I don't know what's wrong.
The Rui's codes worked correctly for the attached file. But I have edited
that file and removed 2 last lines from the file because I could not read
it into R.
These 2 lines were:
"
** CONCUNIT ug/m^3
** DEPUNIT g/m^2
"
When I tried to run the code for my file that has these 2 lines at the end,
it gave me this error:
"
df1 <- read.table(text = txt_table)
Error in read.table(text = txt_table) : no lines available in input
"
The codes before the "df1 <- read.table(text = txt_table)" were run
correctly.
Sincerely

Dear all;
I apologise, I didn't know that I have to cc the list.
Thank you Mr Rui for reminding me.
Let me clarify more.
I have no knowledge of the FORTRAN language. The text file that has been
attached is a model's output file and I know that the format is in FORTRAN.
I want to write a text file exactly similar to the attached text file using
R programming.
The steps below explain my goal:
1- Read the text file without the first 8 and last 2 rows as a dataframe.
Maybe I have removed the last 2 lines, but at the end it had 2 lines
similar the first 8 lines which starts with asterisk.
2- Double the 3rd column values (or multiply by specific number).
3- Insert the removed first 8 lines of the original text file as header in
the dataframe.
4- Insert the removed last 2 lines of the original text file at the end of
dataframe.
5- Write the dataframe as a new text file exactly similar to the original
text file.
I have used excel but when I save it as text file, the format changes and
is not similar to the attached text file.
I will try all your codes in a few hours, cause I am out of office.
Sincerely yours.

Oh, so you want to WRITE a file *like* that.
Use ?sprintf.
(3(1X,F13.5),3(1X,F8.2),3X,A5,2X,A8,2X,A5,5X,A8,2X,I8)
Fortran sprintf
1X a space
3X 3 spaces
F13.5 %13.5f
F8.2 %8.2f
A5 %5s
A8 %8s
I8 %8d
3(...) the translation of ... written 3 times
We can simplify 1X,F13.5 to F14.5
Here's the sprintf() equivalent of the Fortran format,
except you'll need to change the dots to spaces.
"%14.5f%14.5f%14.5f%9.2f%9.2f%9.2f...%5s..%8s..%5s.....%8s%10d\n

Dear Javad,
Perhaps you were looking to read the
table in Air.txt (is this Fortran
format?) into R?
b <- readLines("Air.txt") # The text MIME attachment w/Mailman
footer ...
b <- b[1:(which(b=="")-1)] # Remove the odd Mailman footer (at
end of df)
idx <- max(grep("^\\*", b))+1 # Start of df after header uline
header <- tolower(strsplit(gsub(" +", "_", gsub("\\*", "",
b[idx-2])), "_")[[1]])
b <- read.table(text=b[-(1:idx)], header=F)
colnames(b) <- header[header!=""]
b <- b[,sapply(b, \(i) length(unique(i)))>1] # Remove constant
cols
str(b)
'data.frame': 31324 obs. of 6 variables:
