Thanks for the replies folks,

The sort of thing i had in mind is 

use feature "switch";

for (to be determined) {

when ((s/(\b[A-E]{3}\b)/XXX/g)) {@array[i,1] = $1}
when (s/((Science)|(science))/XXX/g) {@array[i,2] = $1}
when (s/((Math)|(math))/XXX/g) {@array[i,3] = $1} 
when - for all remaining subjects...
when (s/((first|First)\W+(?:\w+\W+){1,10}?([A-E]{3})) #or some similar
+ REGEX returning only the first year entry grades
default {}
}

but i'm concerned that i'm thinking very "C" in my iteration loop for the array

To answer Anonymous monk,

To start with, i'd be very happy with an output that looks like below:

(subject)..|ABB|Maths|Physics|Design&Technology|Engineering

If i can get the progam to do this above, then i'll try and refine it to pull out specific grades

eg ([A-E]{1} in Design|design) returns the grade preceding that subject

Roboticus, thanks for that i may start with a defined array (there are ~200 A level possibilities, but they change very infrequently)and then develop it into one which adds subjects when detected once i get the hang of it.

You have also hit the nail on the head regarding the REGEXes, i was thinking about having a list produced of ones that the regex struggled with, or ones which didn't get any hits to see how i'm missing things too. I'd not thought about multiple passes however, nor repairing misspellings!

really appreciate the input i just need to plough through some text books and remind myself (or learn new things) appropriate to the task in hand

best wishes, Phil
