This status will contain EOF upon reading end of file. Formatted Input Functions. Internal Formatting These procedures convert a string representation of a number into its binary value. That is, they read from a character string variable, not an input stream or file. Each function may be called repeatedly to decode a string of values delimited by white space or embedded in non-numeric characters.
Tokens represent the smallest substrings recognized in the string.
Character and String Functions SPP characters are implemented as integers. Therefore they cannot be treated simply as scalar variables in assignment statements. There is a family of procedures for assigning and otherwise manipulating strings. The converted character is returned as the function value. Note that there are macro definitions to accomplish the same purpose.
