        program test 
        print 10
10      format (' Does an apostrophe appear here'  ' or here', '.')

C               There is no comma separating the first two 
C       apostrophe edit descriptors in this format statement.  
C       The SUN 3 and SPARC compilers accept it anyhow, 
C       and print the output without any apostrophes.  
C       The Alliant compiler (V4.2.40) also accepts it, 
C       but produces an apostrophe after the first "here".
C       Neither compiler produces one after the second "here".

C               Lines 26-34 on p. 13-2 of ANSI X3.9-1978 FORTRAN 77
C       say the comma may be omitted before and after a slash
C       or colon edit descriptor, but do not allow it to be
C       omitted in this instance.  Lines 30-32 on p. 13-5 say
C       "Within the (apostrophe edit) field, two consecutive 
C       apostrophes with no intervening blanks are counted as a
C       single apostrophe", but says nothing about intervening
C       blanks (as here).  

C               The statement seems nonstandard (unless it means
C       to output everything between the first apostrophe and the
C       last, including both intervening apostrophes and the blanks).
C       However, when I try the -ansi option on the SPARC, or
C       the -standard option on the Alliant, the only diagnostic
C       either compiler gives is the presence of lowercase letters.
