2.1.4. Aliases
Command aliases c an b e defined within the menu sy stem. As with the Linux csh shell, aliases tak e
precedenc e over command e xecution. The f ollowing aliases ar e pr edefined in C ortex:error ,pwd ,
chdir ,ls,., and alias .
error
displa ys the Scheme objec t tha t was the “irritan t” in the most r ecent Scheme er ror in terrupt.
pwd
prints the w orking dir ectory in which all file op erations will tak e plac e.
chdir
will change the w orking dir ectory.
ls
lists the files in the w orking dir ectory.
. (period)
prompts y ou f or a jour nal file name and then r un the jour nal file y ou ha ve sp ecified .
alias
displa ys the list of symb ols cur rently aliased .

2.2.1. Numb ers
The most c ommon pr ompt t ype is a numb er. Numb ers c an b e either in tegers or r eal numb ers.Valid
numb ers ar e, for e xample ,16,-2.4 ,.9e5 , and +1e-5 .
•Integers c an also b e sp ecified in binar y, octal, and he xadecimal f orm.
•The decimal in teger 31 c an b e en tered as 31,#b11111 ,#o37 , or #x1f .
•In Scheme , integers ar e a subset of r eals , so y ou do not need a decimal p oint to indic ate tha t a numb er is
real;2 is just as much a r eal as 2.0 .
•If you en ter a r eal numb er at an in teger pr ompt , any fractional par t will b e truncated. For e xample ,1.9
will b ecome 1.
2.2.2. Booleans
Some pr ompts r equir e a y es-or-no r esponse . A y es/no pr ompt will acc ept either yes or y for a p ositiv e
response , and no or n for a nega tive response .Yes/no pr ompts ar e used f or c onfir ming p otentially
danger ous ac tions such as o verwriting an e xisting file , exiting without sa ving c ase, data, mesh, and so
on.
Some pr ompts r equir e ac tual Scheme B oolean v alues (tr ue or false). These ar e en tered with the Scheme
symb ols f or tr ue and false ,#t and #f.

Character str ings ar e en tered in double quot es, for e xample ,“red” . Plot titles and plot legend titles
are examples of char acter str ings . Character str ings c an include an y char acters, including blank spac es
and punc tuation.
2.2.4. Symb ols
Symb ols ar e en tered without quot es. Zone names , sur face names , and ma terial names ar e examples
of symb ols. Symb ols must star t with an alphab etical char acter (tha t is, a lett er), and c annot include
any blank spac es or c ommas .
You c an use wild c ards t o sp ecify z one names when using the TUI. Some e xamples ar e:
•* will tr ansla te as “all z ones ”.
For e xample ,
–/display/boundary-grid * enables y ou t o displa y all the b oundar y zones in the mesh.
–/boundary/delete-island-faces wrap* enables y ou t o delet e island fac es on all z ones
prefixed b y wrap .
•> will tr ansla te as “all z ones visible in the gr aphics windo w”.
For e xample ,/boundary/manage/delete >, yes enables y ou t o delet e all visible z ones .
•^ will tr ansla te as “all z ones selec ted in the gr aphics windo w”.
For e xample ,/boundary/manage/delete ^, yes enables y ou t o delet e all selec ted z ones .
•[object_name will tr ansla te as “all z ones with the name objec t_name ”.
For e xample ,/boundary/manage/delete [box, yes enables y ou t o delet e all z ones of an
objec t with the name box.
•[object_name/label_name will tr ansla te as "all z ones with label_name of objec t_name "
For e xample ,/boundary/manage/delete [fluid/box*, yes enables y ou t o delet e all
zones of an objec t with the name fluid and c ompr ising fac e zone lab els box*.
If you use a wild c ard for an op eration tha t requir es a single z one as input , you will b e pr ompt ed t o
specify a single z one fr om the list of those tha t ma tch the e xpression sp ecified .
> /boundary/manage/name wall* <Enter>

wall-2 wall-4 wall-6
Zone Name [ ]
2.2.5. Filenames
Filenames ar e ac tually just char acter str ings . For c onvenienc e, filename pr ompts do not r equir e the
string t o be sur rounded with double quot es. If, for some e xceptional r eason, a filename c ontains an
emb edded spac e char acter, then the name must b e sur rounded with double quot es.
