Unrecognized token '&' in Fixed Fortran continuation lines

Question

I am editing an old project that uses fixed form Fortran and compiling with IVF compiler. The current issue I have is with continu

Answer 1

Or use the compiler switch -free with .for or .f

Or use the compiler switch -fixed -132 with a .F90 .

In your case I would preserve the .f and cp that to .F90 and then explicitly have the makefile compile the .F90 ...

I normally use -fixed -132 with a .F90 as I often have -d-lines that I retain in the code, and I could not get -d-lines. To work with -free.

Answer 2

In fixed form Fortran, you continue a line with any character in column 6 of the next line, not an & at the end of the 1st line. Try:

      format(//,  10x,'*******************************************',/,
     c  10x,'* DIAGONALS OF THE RESIDUAL COV. MATRIX   *',/,
     c  10x,'*******************************************',//,
     c  2x,'MEASUREMENT',7X,'  RESIDUAL COVARIANCE', /)
