HP Fortran statements DECODE (extension) IOSTAT=integer-variable in-list Description 286 specifies the label of the executable statement to which control passes if an error occurs during statement execution. returns the I/O status after the statement executes. If the statement successfully executes, integer-variable is set to zero. If an end-of-file record is encountered without an error condition, it is set to a negative integer. If an error occurs, integer-variable is set to a positive integer that indicates which error occurred. is a comma-separated list of data items for input. The data items can include expressions and implied-DO lists. The DECODE statement is an HP extension that is provided for compatibility with other versions of Fortran. The internal-I/O capabilities of the standard READ statement provide similar functionality and should be used to ensure portability. The DECODE statement translates formatted character data into its binary (internal) representation. Examples The following example program illustrates the DECODE statement: PROGRAM decode_example CHARACTER(LEN=20) :: buf INTEGER i, j, k buf = 'XX1234 45 -12XXXXXX' DECODE (15,'(2X,3I4,1X)', buf) i, j, k ! The equivalent READ statement is: ! READ (buf, '(2X,3I4,1X)') i, j, k PRINT *, i, j, k END PROGRAM decode_example When compiled and executed, this program produces the following output: 1234 45 -12 Related statements ENCODE and READ Chapter 10
