Re: [fpc-pascal] basic question on begin, end;
Personnally I go even further ;-) if something then begin some multi-line code here end else begin some multi-line code here end; ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

Bye Little information ;-) You could try a few things to get more data about what is the point where the program breaks: * Add some log information (write to a log file, not through exception) in the lpr file before it starts the application run. * Add to the main form in the create constructor and in the formcreate event some log information. If the programs doesn't starts at all, then probable you have any problem at binary level. That is usually hard the find. You could ask the customer to run it from cmd prompt. Sometimes it displays some informative message. Once I had the problem that 32bits worked fine in my PC, but failed in customer's system. The problem was that I was using firebird but the customer had installed 64bits version, so the client library fbclient.dll was 64bits and exe 32bits. I copied a 32bits fbclient.dll to the exe directory and everything worked fine. -- Saludos Santiago A. ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

This use of whitespace as block delimiter is why I never could cope with Python when I was working (now retired). Begin-end are really big helpers to correctly structure loops etc and I use them all the time to make things clearer. Also putting begin right below if, for, while etc makes it much easier in Lazarus to see what happens in multi-level code when one is selecting begin or end since they match vertically. So I never do: if something then begin some multi-line code here end; Instead: if something then begin some multi-line code here end; And of course as has already been pointed out the original question's example code fundamentally changes execution with or without the begin-end pair! -- Bo Berglund Developer in Sweden ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
