crystal report help file

[digitalquatro]

Hi all...
I'm a new at crystal reports.
Can i put something like this in my report formula

YR=SUBS(DTOS(DATE()),3,2)

YR+' '+LEFT(ALLT(STR(SOMETHING.CLV_ADUA)),2)+' ';
+SOMETHING.CLV_AGE+' '+SOMETHING.NO_DOC+"'"

See I want to print the variable "YR" followed by some fields.

P.D.
Where can i get the help file for crystal reports ?
Thanks in advance...
