thanks a lot. But there is one problem - this is my
fault. The KEY1, KEY2 don't exactly look like this. There are six KEYS. Three are related to KEYS, but the
rest of them are A_BEG A_END, B_OPTIONS, and I need to
extract information between them. I used one variable $op=KEY1|KEY2|KEY3|A_BEG|A_END|B_OPTIONS to store all
the alternatives, and tried to use
my @values = $line =~ /$op.*$op/g;
But didn't work as i expected. Are there any problems. please help me with it. thanks again.
Are they always ordered in the above manner or is it possible for B_OPTIONS to occur before KEY3, etc.??
The line might be one of the following: KEY1 3 4 T KEY2
KEY1 3 4 T KEY2 456 67 KEY3
KEY1 3 4 T KEY2 456 67 KEY3
