From: CapCity on 2 Apr 2010 13:18 In the following statement: read(strtmp(:j-1),'(i)') Is the (i) the same as (i1)? If not, what does it mean? Thanks!

The use of just I as a format edit descriptor is non-standard. For the compilers I am familiar with, it is allowed as an extension and says to have the processor determine the width based on the type/kind of the corresponding I/O list element. For example, in Intel Fortran, the width chosen is 7 for INTEGER(1) and INTEGER(2), 12 for INTEGER(4) and 23 for INTEGER(8). -- Steve Lionel Developer Products Division Intel Corporation Nashua, NH For email address, replace "invalid" with "com" User communities for Intel Software Development Products http://software.intel.com/en-us/forums/ Intel Software Development Products Support http://software.intel.com/sites/support/ My Fortran blog http://www.intel.com/software/drfortran

Though I'm more used to seeing that kind of extension on output than input. I might guess that it is intended to be something like list-directed input, but that is just a guess. The only safe statement is that it is nonstandard, as you said. If I were porting it and had no other information, I'd probably be inclined to try to substitute list-directed input (given at least an f90 compiler, as list-directed internal input was nonstandard in f77). -- Richard Maine | Good judgment comes from experience; email: last name at domain . net | experience comes from bad judgment. domain: summertriangle | -- Mark Twain |
