PAUSE _ _ _ _ _ _ _ _ _ _ _ _ command

The pause command, given in an interactive file, stops operation and asks if you want to continue or not.

examples:

An interactive file is running, and at some point you see the question

 

				   Cont? (Y or N) 

If you type

 

ykey{Return}

the file continues to run until the next pause or the end.

If you type

 

nkey{Return} 

you will get a numbered REDUCE prompt, and be allowed to enter and execute any REDUCE statements. If you later wish to continue with the file, type

 

cont; 

and the file resumes.

To use pause in your own interactive files, type

pause;in the file wherever you want it.

pausedoes not allow you to continue without typing either y or n. Its use is to slow down scrolling of interactive files, or to let you change parameters or switch settings for the calculations.

If you have stopped an interactive file at a pause, and do not wish to resume the file, type end;. This does not end the REDUCE session, but stops input from the file. A second end; ends the REDUCE session. However, if you have pauses from more than one file stacked up, an end; brings you back to the top level, not the file directly above.

A pause typed from the terminal has no effect.
