DISPLAY                   PSAM Commands                   DISPLAY



NAME
     display, undisplay - display variables on entry to psam

SYNOPSIS
     display [ <variables> ]
     undisplay

DESCRIPTION
     The display and undisplay commands control the  printing  of
     variables  on  entry to psam. Without parameters the display
     command shows the variables in the display  list,  which  is
     initially  empty.  Any parameters to display are appended to
     the display list. The undisplay command  clears  the  entire
     display list, i.e. variables cannot be 'undisplayed' indivi-
     dually.

     Each time psam is entered the display list is checked to see
     if there are variables to display.  If there are the display
     list is passed to the print command. The syntax  and  seman-
     tics  of the <variables> parameter is therefore identical to
     that of the parameter of the print command.

     No checking of duplicate, unknown or  syntactically  invalid
     variables is performed by display.

EXAMPLES
     display scal1            append the variable  scal1  to  the
                              display list.

     display mat2(1,3:5)      append  the  subscripted   variable
                              mat2(1,3:5)  to  the  display list.
                              [On entry to psam row 1 columns 3-5
                              of MAT2 will be displayed.]
