 Posted: Tue Jan 22, 2013 4:48 pm Post subject: error program |
 |
|
hi, I'm a university student of engineering and I need to learn how to use clearwin because I have to create a program for my final graduation! then I found the guide of clearwin+ and I started to learn but the program give me an error and I don't understand what I have to do!
the guide writes:
1 WINAPP 0,0,'CWP_ICO.RC'
2
3 PROGRAM factor1
4 IMPLICIT NONE
5 INCLUDE <windows.ins>
6 INTEGER ans,number
7 number=1
8 ans=winio@('%ca[Number Factoriser]&')
9 ans=winio@('%il&%',1,2147483647)
10 ans=winio@('Number to be factorised: %rd',number)
11 END
silverfrost answer me:error 28 - PROGRAM cannot be declared inside PROGRAM block (perhaps missing CONTAINS or END statement?)
where is the problem? please help me and sorry for my terrible english!

Tutorial inside the guide is horribly dated using Fortran77 syntax. I would probably rewrite it in Fortran90, use modules and get rid of common blocks...
Following should compile and run fine:
| Code: |
WINAPP
program factor1
use mswin
implicit none
integer :: ans, number
number=1
ans=winio@('%ca[Number Factoriser]&')
ans=winio@('%il&',1,2147483647)
ans=winio@('Number to be factorised: %rd',number)
end program factor1

By the way... Your english is just fine. |
