hi i am woking on lex
i want to define a class as KEY which will include some other words

i.e

KEY [HELLO]

but when i do this lex recognizes KEY even when only 'H' is typed, but i want it to be recognized only when the whole word 'HELLO' appears

i would also like to add few more words in the KEY class...how can i do that?

thank you

heres the answer

KEY Hello foo

now Hello and foo both fall in the KEY class and in the rules section of lex source file you 'll do

{KEY} printf("KEY found");

thankz
