List of Code Examples

note: you should access the code examples from September 7^th lecture by going to the lecture (which is #4)

FORTRAN

Example1

Example2 – note that this is the one that would not compile correctly

Here are some others to play with – they may or may not compile – see if you understand them

Illustrates an array

Illustrates use of end =

Illustrates using integer division

Illustrates use of an if statement

Code examples discussed in both classes – all of which illustrate

use of computed go to statement.

Example2v1 has hard coded value for I

Example2v2 gets a single value from user for I

Example2v3 loops and gets multiple values from user for I

Example2v4 provides a better prompt

Example2v5 illustrates use of ERR= to keep program from bombing on incorrect input

Code examples discussed only in early class due to building evacuation

Silly

shows use of FORMAT statement to print only a label (10)

shows FORTRAN’s pass by reference parmeters

shows what used to happen when literals were passed as reference parameters

shows alternate FORMAT statements to print data in same way (12 and 13)

shows possible placement of SUBROUTINE subprogram in relation to calling program

shows use of CALL statement to execute SUBROUTINE

MySub

shows use of CALL statement

shows possible placement of SUBROUTINE subprogram in relation to calling program

shows use of continuation card

shows SUBROUTINE to swap two numbers

shows that a blank line is okay

Code example NOT discussed in class which doesn’t produce desired output. See if you can figure out what’s wrong
