Decode an integer from a character string.

This subroutine decodes an integer from a character string. The string may contain leading or trailing blanks, but otherwise should contain only digits and an (optional) leading sign ('+' or '-') character.

If the string is empty or contains all blank characters, then num is returned with a value of 0.

Parameters

[in]	str	- character*(*): String.
[out]	num	- integer: Value decoded from str.
[out]	iret	- return code: 0 = success -1 = string contained one or more illegal characters
