Fortran write character " into CHARACTER variable

Question

I have a Fortran file where at a certain point I have to write a command line into a batch file. This works well:

CHARACTER*260 TLINE1
. . .
TLINE1= 'c:\Programme\OriginLab\Origin2015\Origin92_64.exe'
. . .   
WRITE(4,'(1A260)')TLINE1

and in my Batch-File I get

c:\Programme\OriginLab\Origin2015\Origin92_64.exe

Now I want to add another Text. I want to have in my Batch-File this line:

start "" c:\Programme\OriginLab\Origin2015\Origin92_64.exe

My problem now is that I cannot write the ""-characters into that line directly. I tried this but it won`t work:

CHARACTER*260 TLINE1
. . .   
TLINE1= 'start "" c:\Programme\OriginLab\Origin2015\Origin92_64.exe'
. . .
WRITE(4,'(1A260)')TLINE1

Do I have to wrap these characters somehow?

edit:

I tried:

TLINE1= 'start '"' c:\Programme\OriginLab\Origin2015\Origin92_64.exe'
TLINE1= 'start '""' c:\Programme\OriginLab\Origin2015\Origin92_64.exe'
TLINE1= 'start '"''"' c:\Programme\OriginLab\Origin2015\Origin92_64.exe'

but nothing worked. Fortran didn`t compile. Message: error#6054 A character data type is required in this context

I got the solution for my question:

  TLINE1= ' c:\Programme\OriginLab\Origin2015\Origin92_64.exe'
  T1A = 'start "" '
  TLINE2 = ' -c %TEMP%\amix'
  TLINEGES =trim(T1A)//trim(TLINE1)//trim(TLINE2)

Please *never* use *"It won't work"* or *"it doesn't work"*. It does not tell us anything useful. Tell us what happened. What was exactly wrong? — Vladimir F Героям слава, Feb 07 '18 at 10:08

I tried the solution given in the link - still got this error — user3443063, Feb 07 '18 at 10:43
You don't need to try any of those three added (and each is wrong): as the linked answers try to explain, the literal `'"'` is a double quote. There's no need to nest, or use the "triple" form. Your `TLINE1= 'start "" c:\Programme\OriginLab\Origin2015\Origin92_64.exe'` should be correct. Please give the result of that. — francescalus, Feb 07 '18 at 10:53
When doing so I get Error #5120 Undetermined character constant, Compilation is aborted — user3443063, Feb 07 '18 at 10:58
I did it with 2 variables that I pasted together. This worked fine: TLINE1= ' c:\Programme\OriginLab\Origin2015\Origin92_64.exe' T1A = 'start "" ' TLINEGES =trim(T1A)//trim(TLINE1) — user3443063, Feb 07 '18 at 11:09
Can you update the question instead with proper formatting and a concise explanation of what you did? (aim, code, error message) — Pierre de Buyl, Feb 07 '18 at 11:10
There is no reason that a plain `TLINE1= 'start "" c:\Programme\OriginLab\Origin2015\Origin92_64.exe'` should not work. You might have a temporary workaround but it is a stretch to call it a solution in the perspective of other readers on SO having a similar problem. — Pierre de Buyl, Feb 07 '18 at 11:16
