WRITING BOTH CHARACTERS AND DIGITS IN AN ARRAY
===

I have a Fortran code which reads a txt file with seperate lines of characters and digits and then write them in a 1D array with 20 elements.
This code is not compatible with Fortran 77 compiler Force 2.0.9. My question is that how we can apply the aformenetioned procedure using a Fortran 77 compiler;i.e defining a 1D array nd then write the txt file line by line into elements of the array?

Thank you in advance.

the txt file is attached.
