Functional Details

This module uses a format-control string (format) to extract values from a specified input string (input).

Note: The control string resembles a C-language scanf format string.

The "%" symbol in the control string specifies that extraction is to begin at the corresponding position in the input string. The character immediately following this symbol specifies the type of value to be extracted:

c: single character

d: integer

f: floating point (with a fixed number of digits after the decimal point)

g: general (scientific notation if appropriate)

s: string.

The number of outputs is equal to the number of extractions specified in format.

Example

Given the statements:

string = "temperature = 45.8  index = 4 color = red"
format = "temperature = %f index = %d color = %s"
output1, output2, output3 = Format(string, format);
