verbatim environment inside center environment 1 41 (8/13/2008 10:58:34 PM) comp.text.tex I had hoped the following would produce two centred lines of output. \documentclass{article} \begin{document} \begin{center} \begin{verbatim} Line 1 \end{verbatim} \verb+Line 2+ \end{center} \end{document} In... harper

internal file and namelist 12 46 (7/21/2008 10:33:15 PM) comp.lang.fortran Can an internal file be used for f2003 namelist I/O? The f95 standard 9.2.2.2 prohibits it. If there is a corresponding prohibition in the f2003 standard I failed to find it. MR&C "Fortran 95/2003 Explained"... harper

merge of character strings 3 44 (6/13/2008 3:10:21 AM) comp.lang.fortran Is this program standard-conforming? Two f95 compilers gave the output I had expected, two others gave compile-time crashes. I suspect the point at issue is merge(tsource,fsource,mask) where the lengths of th... harper

Floating-point precision 3 33 (2/23/2008 1:36:23 AM) comp.lang.fortran Given the following program, which works if and only if the compiler allows higher than double precision, I was surprised to find that a certain compiler, for which pdp = 15, php = 18, printed y with only 8 c... harper

character array constructor question 3 77 (11/19/2007 11:00:22 PM) comp.lang.fortran Is the following program standard-conforming (a) in f95 (b) in f2003? Some compilers print out = aabbccddee should be aabbccddee but others don't, so I'm suspicious. PROGRAM testchararray IMPLICIT NONE ... harper

association of pointers 6 39 (11/13/2007 11:09:02 PM) comp.lang.fortran In an attempt to understand pointers, I wrote the following: PROGRAM testassoc3 INTEGER, TARGET :: beast = 666 INTEGER, POINTER :: ptr => NULL() ALLOCATE(ptr) ptr = beast PRINT "(A,I4)",' After ptr... harper

assumed-length character variable 2 44 (10/29/2007 8:54:30 PM) comp.lang.fortran The PRINT *,x//'BAR' statement in the program below is bad f77 because x is an assumed-length character variable: see the f77 standard 6.2.2. I couldn't find any such prohibition in f95, and six f95 compilers... harper

sanserif bold for dyadics 2 21 (9/18/2007 12:34:24 AM) comp.text.tex A common font for dyadics is sanserif upper case bold roman. How does one put them in a document that is otherwise in Computer Modern? (I can manage upper case bold roman, but my problem is sanserif.) -- John... harper

Repeating main index entry if pagebreak at sub-entry 1 27 (7/24/2007 2:45:16 AM) comp.text.tex I am using \documentclass{book}. If an index entry of the book has a lot of sub-entries, and a page break or column break occurs among the sub-entries, how does one get the main entry to be repeated at the top ... harper

scope of implied-do variable 4 38 (6/8/2007 2:27:49 AM) comp.lang.fortran IMHO the program below is valid f95, because the f95 standard 14.1.3 says the scope of i in the implied-do in the line 2 array constructor is just that implied-do. If so, it can't be the same variable as the ... harper

convert a date to a number of days 14 66 (10/25/2008 9:22:50 PM) comp.lang.fortran Hi everybody, I would like to know if it exists an intrinsic function in Fortran to convert a date to a number of days ? For example the 25/10/2008 would be converted to: 2008*(365+1/4) + (31+29+31+30+31+30+... elodie.roux (82)

Square root of a negative rral value 86 74 (11/5/2008 11:33:03 PM) comp.lang.fortran I mentioned in another post that I was converting a mainframe Fortran IV program to F77 (and F90).
