Differences SYS(100) AND SET('CONSOLE') 1

[weedz]

Hello there,

Can anyone provide me with any info regarding SYS(100) and SET('CONSOLE'), concerning any differences between these two statements ??

Both should return the 'set console' setting, according to the MSDN but in my app both show opposite values (SYS(100) shows 'OFF' as where SET('CONSOLE') returns 'ON'.

Thanks in advance,

While FPD/FPD list CONSOLE as an Option for the SET() function, VFP 3/5/6/7 don't. I'm not sure what ? SET(CONSOLE&quot actually represents - it's always ON. Note: ? SET(CONSOLE&quot is also &quot;wrong&quot; - always ON - in FPD/FPW 2.6a - so much for documentation <g>.

OK. Let me see if I can explain this without muddying the water:

They SYS(100) function is used in conjunction with SET('CONSOLE') in order to restore the SET CONSOLE setting after an error occurs.

The important clause in the VFP help for the SET CONSOLE command:
Important An error always sets SET CONSOLE to ON. Use SYS(100) to check the SET CONSOLE setting before the error occurred.

Paste the following into a PRG and run it:
ON ERROR *
MESSAGEBOX('SET CONSOLE IS '+SET('CONSOLE'),0,'Before')
MESSAGEBOX('SYS(100) IS '+SYS(100),0,'Before')

OH-BOY && last I checked, OH-BOY was not a valid VFP
&& function, thus throws an error

MESSAGEBOX('SET CONSOLE IS '+SET('CONSOLE'),0,'After')
MESSAGEBOX('SYS(100) IS '+SYS(100),0,'After')

Rick,

I'd guess the reason SET CONSOLE is always returning ON, in your case, is because you are issuing it from the command window and it cant be set from there. Jon Hawkins

Thanks Jon & Rick,

These are the answers that give me some insight. As you stated the console setting was indeed set to ON by an error in my case. That is how I got to the question.

Thanks again.
