str_character_count_c

	count.i4.v = str_character_count_c(string.i1a.r, length.i4.v,
					   character.i1.v)

	This routine will return the number of occurrences of a specific
	character in a string.

	string		string to search
	length		length of string to search (a value of zero

	character	character to find

	This function returns status values as follows:

	CBS_INVARG		invalid length passed
	otherwise		number of occurrences of specified character

	This function requires the following include files:

	cnsparam_h, cbslib_h, acnet_errors_h
