LOGICAL FUNCTION LSAMEN( N, CA, CB ) CHARACTER*( * ) CA, CB INTEGER N
LSAMEN tests if the first N letters of CA are the same as the first N letters of CB, regardless of case. LSAMEN returns .TRUE. if CA and CB are equivalent except for case and .FALSE. otherwise. LSAMEN also returns .FALSE. if LEN( CA ) or LEN( CB ) is less than N.
N (input) INTEGER The number of characters in CA and CB to be compared. CA (input) CHARACTER*(*) CB (input) CHARACTER*(*) CA and CB specify two character strings of length at least N. Only the first N characters of each string will be accessed.
