DESCRIPTION

index(a1,a2) returns index of first occurrence of string a2 in string a1 , or zero if it does not occur. 

rindex(a1,a2) returns index of last occurrence of string a2 in string a1 , or zero if it does not occur. 

lnblnk( a1 ) returns the index of the last non-blank character in a1 .  This is useful since all f77 character objects are fixed length, blank padded. 

Note that the intrinsic function len returns the declared size of the character string argument.
