Rule problem

[os]

Hi there,

 

I did just start in working with flex and have a thing with

the 2 following lex codes I don't understand :

1.)

AXIS   [XYZABC]

%%

G25{NAME}+     { /* some action  */ }

%%

 

2.)

%%

G25[XYZABC]+   { /* some action  */ }

%%

 

A string like "G25XYZ" isn't recognised as a valid rule with 1.),

but with 2.) it is ! Any ides why ?

 

 

Thanks
