string - Fortran77整数を文字列にキャストする

Question

興味深いことに、Fortran77で整数を文字列にキャストする方法を見つけようとしていました。私は出くわしましCHAR(I)たが、これはASCIIインデックスIをその位置の文字に変換します。Fortran77で整数を文字列に単純にキャストする方法はありますか？逆はどうですか？

Answer 1

The Fortran way is to write the value of the integer into a string variable; this operation is known as an internal write. I'm heading out the door now so won't check this, and I have an ethical objection to writing FORTRAN77 or helping anyone else write it, so make no guarantee that the following doesn't contain bits of more modern Fortran.

First declare a character variable to receive the integer

character(len=12) :: int_as_string

then write the integer into it as you would normally write an integer to any other channel such as stdout

write(int_as_string,'(i12.12)') my_int

I expect you'll want to set the format for writing the integer to something that suits you better
