From: rfengineer55 on 27 Jun 2010 11:28 Hello, I' working on another of a large collection of FCC Fortran programs compiled in VAX VMS Fortran. There are variables in this program named Class4 , Class3, Class2, and Class1.They are declared as type Logical. There are other variables such as class_out declared as type character. All of my variables with class as part of their name, are generating compiler errors. Here is one - When the compiler hits these, I get an error saying that #5082 syntax error, found IDENTIFIER '_out when expecting one of : (%:, ==> The line in the code associated with this error is - class_out = 'OA" An error message I get associated with the Logical variables is $5082 Syntax error, found INTEGER_CONSTANT '4' when expecting one of : (%:,,==> The line of code associated with this error is - class4 - .false. I am not aware of anything in Fortran where Class has any kind of reserved meaning, There is some mention of Class made in the Visual Studio 2008 book, but I have not doug deeply into that. Before I do, I thought to run this interesting compiler situation by the list members. What do you think? Thanks beforehand, for the help. Jeff RF ENGINEER55

If that's really so, fix that first. Otherwise, insufficient context given because in isolation the line looks ok. > An error message I get associated with the Logical variables is $5082 > Syntax error, found INTEGER_CONSTANT '4' when expecting one of : > (%:,,==> > > The line of code associated with this error is - > > class4 - .false. That's got a problem of an "-" instead of an "=" in what appears should be an assignment statement. From the above, I'm guessing this was optically scanned from a printed listing and it's full of errors from that process. --

IVF recognizes a CLASS keyword. 2. Your compiler is treating blanks as insignificant, so it parses "CLASS1" like "CLASS 1", and it's expecting something different after "CLASS". You'll have to find a way to make it treat blanks as significant (just like in most other languages). This may be a matter of specifying free-format source instead of fixed-format (or whatever they're called). If your source files are really in fixed format, you may have to change other things, like line continuations, but it will be worth it in the end. Louis

The errors you found are a result of my sloppy typing. In the source code, the character delimiters are actually OK class_out = 'AB' Same for the other line. In the sorce, it actually reads - class4 = .false. I'm truly sorry for not catching this before I posted. I will be more careful in interest of everyone's time. Thanks, Jeff RF ENGINEER55

Given your observations and suggestions, I'm going to do some digging in the VS 2008 and find out more about the Class references that I briefly noted. Hopefully there will be an easy fix. I I can convince the compiler to treat class1 as written rather than parsing it as class 1 like you're saying, I should be good to go. This Fortran source I'm working with is large, so I hesitate to make changes in the variable names because that could have far-reaching consequences. I would normally just change the variable name and e done with it, inthe case of a smaller program. Louis, thank you for your thoughts on this. Jeff RF EGINEER55 |
