-exx closing the program without warning?

[IvanisIvan]

G'day,
today I was messing about and wrote this piece of code:

Code: Select all

dim array(10) as integer = {1,6,3,7,2,6,7,9,2,1}
for i as integer = -1000 to 9 step 1
    print array(i)
next i
sleep

I expected it to immediately crash due to an out of bounds error, and to my shock, it didn't! I learnt about compiler commands so I assumed that -exx is the one I should add. Now, it does successfully cause the program to crash, but it leaves no error message. I have tried putting in -w all in the compiler command section, but it does not seem to help. Could someone please help me with this? Additionally, why is -exx not put on by default? This seems dangerous!

Code: Select all

command:"<$fbc>"  "<$file>" -exx -w all
run:"<$file>" <$param>

To be able to see the error, you need to compile and execute the program from the command line. Otherwise a console window opens and closes immediately.

Because it adds both run-time costs and bloats the executable. That's why most programming environments allow for a 'debug' build (with run-time checks and other features, usually selected via switches) and a 'release' build (with very little or no debug features enabled).

I see. Is there a way I can make the console window not close immediately?

What IDE are you using ?

With fb 1.09 you no longer need to put compiler options in an ide, you can put them in code.
But that is optional of course.

Code: Select all

#cmdline "-exx"
dim array(10) as integer = {1,6,3,7,2,6,7,9,2,1}
for i as integer = -1000 to 9 step 1
    print array(i)
next i
sleep

In fbide here is the run command to keep the console open:
In the ide;
view->settings->freebasic, in the Run command box:

cmd /c "<$file>" <$param> & pause

I believe some other ides have an option for the run command.
