To take the above exam, I have been a good boy and read the C/Front pdf manual and read the C/ODBC pdf manual. Although I haven’t managed to actively used them with Navision, I found the manuals very illustrating. In the exam it asks for what are the advantages of C/ODBC over C/Front and vice versa! The above manuals don’t cover these issues, can anyone recommend a manual that does. Also in the w1w1codbc.pdf manual (3.60 version) it says for coverting identifiers… All Except Space Letters, numbers and symbols are transferred unchanged. Spaces, dots and question marks are converted to underscores (). In another part of the above manual it says… All Except Space Letters, numbers, symbols and dots are transferred unchanged. Spaces are converted to underscores (). Which one is correct? Thanks for your help!
