Matching pattern in PERL

Hello,
 I need to verify a string from the command line in a PERL script.  I  need to make sure that the string has the following format:

ABS <A-Z><A-Z><A-Z> <0-9>.<0-9>.<0-9> <A-Z><number> <A-Z><number>

here is a sample:

ABS MSI 9.8.5 A209 B203
ABS HGF 9.8.5 A1234 B6456

i.e. of not valid strings:

SABS MSI 9.8.5 A209 B203
ABS HGF 19.8.5 A1234 B6456
ABS MSI 9.84.5 A209 B203
ABS HGF 9.85.5 A1234 B6456
ABS MSI 9.8.5 A209 B203D
ABS HGF 9.8.5 AB1234 B6456

(in words: ABS 3 letters, space, number.number.number letternumber letternumber)
String needs to start with ABS, then the rest of the sequence.

This is what I was trying but it is not working:
($LABEL =~ /^ABS [A-Z][A-Z][A-Z] [0-9]\.[0-9]\.[0-9] A[0-9][0-9][0-9] B[0-9][0-9][0-9]/))

Thanks

The + means one or more of what is before it.
The $ at the end means end of line (a $ in the middle will be interpreted as a variable name).

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

ozo had answered your original question... the points should have gone to him (or at least a split)

Oops!  I didn't noticed.  Very sorry about that.
 Is there a way to go back and fix it?
