FORTRAN Statements 2.49 GUESS Statement GUESS [: block-label] The GUESS statement is an extension to the FORTRAN 77 language. The GUESS statement marks the beginning of a block of statements for which a certain assumption or hypothesis has been made. This hypothesis may be tested using logical IF statements in conjunction with QUIT statements. The ADMIT statement may be used to mark the beginning of an alternate hypothesis. The END GUESS statement is used to mark the end of a series of GUESS-ADMIT blocks. Example: CHARACTER CH READ *, CH GUESS IF( CH .LT. ’a’ )QUIT IF( CH .GT. ’z’ )QUIT PRINT *, ’Lower case letter’ ADMIT IF( CH .LT. ’A’ )QUIT IF( CH .GT. ’Z’ )QUIT PRINT *, ’Upper case letter’ ADMIT IF( CH .LT. ’0’ )QUIT IF( CH .GT. ’9’ )QUIT PRINT *, ’Digit’ ADMIT PRINT *, ’Special character’ END GUESS END An optional block label may be specified with the GUESS statement. For more information, see the chapter entitled "Program Structure Control Statements" on page 193. GUESS Statement 83
