Console current path

 [1/5] from: jrdrp:blueyonder at: 17-Dec-2001 19:32


Hi all, Why does my console apparently change directory after an error occurs in program (halted etc.)? Console session example below show:->
>> do/args %myprogs/ftget.r "FTX1"
Program FTGet begin ["FTX1"] Invalid FTSE Index argument : FTX1
>> do/args %myprogs/ftget.r "FT1"
** Access Error: Cannot open /C/rebol/view/myprogs/myprogs/ftget.r ** Where: halt-view ** Near: do/args %myprogs/ftget.r "FT1"
>>

I've heard the reason, (from RT), but forgotten it. But if it happens, change your 'do path to a full path and your program will run again without you having to close the console down and start again. (No doubt someone could write you/us a reset-path function we could add to our REBOL startups?)

That's a bug. Please submit it to feedback. 'do needs to switch directories in order to run the script (scripts expect their own directory to be current), but is supposed to switch back after the script has completed. Apparently that does not happen if an error occurs. -- Holger Kruse [holger--rebol--com]

Rebol changes the current directory to %myprogs/ so that %ftget.r is running with the correct current directory. When the error occurs in %ftget.r, the current directory is still %myprogs/ so that's why the current directory seems to have changed for the console -- you're still in the context of %ftget.r, which is different from where you were before. I hope that helps! Andrew Martin ICQ: 26227169 http://valley.150m.com/

Just checked what feedback told me about this. (I submitted it way back in May 2000)... After running a script which exits with an error, the current directory becomes the one where the script was in. You can check this out with the WHAT-DIR command. I wasn't told then it was a bug so I've always assumed it's intended REBOL behaviour... -- Carl Read
