The list consists of keywords separated by commas or colons. Since all these warnings are on by default, include a keyword prefixed by no- to turn off a particular warning. There are three special keywords: all to turn on all the warnings about array arguments, none to turn them all off, and help to print the list of all the keywords with a brief explanation of each. If list is omitted, -array is equivalent to -array=all, and -noarray is equivalent to -array=none. The warning keywords with their meanings are as follows:
For compatibility with previous versions of ftnchek, a numeric form of this setting is also accepted: the list is replaced by a number from 0 to 3. A value of 0 turns all the warnings off, 1 turns on only dimensions, 2 turns on only size, and 3 turns all the warnings on.
Note: A warning is always given regardless of this setting if the actual argument is an array while the dummy argument is a scalar variable, or if the actual argument is a scalar variable or expression while the dummy argument is an array. These cases are seldom intentional. (To turn off even these warnings, use -arguments=no-arrayness.) No warning is ever given if the actual argument is an array element while the dummy argument is a scalar variable. Variable-dimensioned arrays and arrays dimensioned with 1 or asterisk match any number of array elements. There is no check of whether multi-dimensional arrays agree in the size of each dimension separately.
