Prototype

load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"

	procedure indStrSubset (
		str        [1] : string,  
		str_subset [1] : string   
	)

	return_val [*] :  integer

Arguments

Variable of type string which will be searched for a substring.

Variable of type string specifying the subset.

Description

Return True if str_string is contained within the variable str; otherwise return False. The inputs, str and str_subset, are converted to characters. If str_subset is a subset, then the indices [subscripts] of the character sequence are returned. If str_subset is not a subset of str, then a integer missing value is returned.

Examples

Example 1

If the string "orange" is a subset of "apple_orange_banana", return the indices of chararacter locations.

   aop = "apple_orange_banana"   
   o   = "orange"               
   ii  = indStrSubset(aop, o ) 
   if (.not.ismissing(ii)) then  
       print(ii)
   end if
