Using STREGEX/STRMID [message #71283]

Hello,

I'd like to get the "label" (i.e. 1033) from this string:

IDL> str = '; ROI name: EVF: Layer: pts_slant.shp (Label=1033)'

...and I was wondering if there is a more elegant/efficient way of
doing this than:

IDL> pos0 = stregex(str, '=')+1
IDL> posn = stregex(str, ')')
IDL> print, strmid(str, pos0, posn-pos0)

IDL prints:

1033

Thanks!
