Hey there!
Here is what I have:
FOR f=0, N_ELEMENTS(foldername)-1 DO BEGIN<-----
IF test EQ 1 THEN BEGIN -
IF test EQ 1 THEN BEGIN -
IF test EQ 1 THEN BEGIN -
PROBLEM >--------------------------
ENDIF
ENDIF
ENDIF
ENDFOR
What I'd like to do:
If an error in the third IF statement occurs/ if the statement does not match the criteria, then the FOR-loop should skip the current file (f=n) and continue with the next file (f=n+1).
I saw that there is a function called CONTINUE but I couldn't make it work yet.
Does anyone have solution for this problem?
Thank you very much!
Greetings

Hi,
I'm not sure what "PROBLEM" means, therefore I've made two versions. The easiest one:
pro testEasyContinue
for i=0,10 do begin
if i eq 5 then begin
if i eq 5 then begin
if i eq 5 then begin
print, 'skip this one!'
continue
endif
endif
endif
print, i
endfor
end
and the complicated one that catches an error:
pro testContinue
for i=0,10 do begin
if i eq 5 then begin
if i eq 5 then begin
if i eq 5 then begin
Catch, theError
if theError ne 0 then begin
print, 'skip this one!'
continue
endif
a = b ;generate error
endif
endif
endif
print, i
endfor
end
Both give the same result:
0
1
2
3
4
skip this one!
6
7
8
9
10
I hope it helps.
Cheers,
Helder
