You can, however, force a display of the values of the variables in an active screen from
within a program using the sprint command. The following one-line program will show
all the records, as required
f
1r 5 t : Let x =0: wh; lex <c au nt () : 5 p ri nt : n ext: let x=x+ 1 : end IN hi Le
If there IS no active screen sprint has no effect.
Remember that the display command uses fhe standard layout. It will always replace
any screen layout with
ItS own simple list of the fields of the current record of tile current
file. You must therefore ssave your screen layout before you next use display. If you
do not, your screen layout will be replaced and you will not be able to get It back again
except by redesigning
It with sedi!.
