The source does not bother with the MODULE protocol of F90 and later, and so the type of function CUSIPCHECK must be declared in all routines wishing to invoke it. However, the F90 feature of having the END statement of a subroutine or function give its name is to valuable to ignore. The function returns a character code rather than an integer, since the presumption is that it is to be compared to the check character of the code being inspected, which is known as a character not an integer. This means some blather when extracting the eight characters to be presented to CUSIPCHECK and comparing the result to the ninth character, but the test can be done in one expression.
 
There is no checking that only valid characters are presented, nor that eight-character codes only are offered, though the compiler might complain if the function were to be invoked with a text literal of the wrong size. In the absence of such checks, there need be no added complications to support a scheme for reporting such errors. <langsyntaxhighlight lang=Fortran> CHARACTER*1 FUNCTION CUSIPCHECK(TEXT) !Determines the check sum character.

Output: standard output is to I/O unit 6, and free-format (the *) will suffice for this. Each line output starts with a space (in case it is to go to a lineprinter, with carriage control), which is convenient for layout here.

This would have worked first time, except that a fymgre frmble caused the omission of the digit 2 from the text of VALID. The benefits of checking checksums reach to unexpected places!
