You need to provide more information:

1) What operating system? Do you need something operating system independent?
2) What screen? Web Browser? pty? tty? Windows command shell? Inter-galactic-sub-etha-pan-dimensional-rendering-device?
3) Have you tried: tput clear

Hi Senthil,

I usually write this small program and catalog it on jBase level. The
program more or less imitates the old UniVerse "CS" command, i.e. it
clears any active select list, clears the screen and turns off any
screen attributes. Not sure if it works on all terminals though...

PROGRAM CS

CLEARSELECT

CRT @(-1):@(-128):

END

Cheers,

Ryan

PROGRAM CS

CLEARSELECT

However, this has the side effect of clearing the default select list too and is only runnable from the jSHELL if you CATALOG the program.

If you are using *-nix just type 'clear'

Create a VOC by name CLS (or anything you like) as follows:

File VOC , Record 'CLS'  
Command->
0001 PQN
0002 T C

Save it. Now whenever you wish to clear your screen just type CLS & hit Enter.

T means go to terminal, C means clear screen based on terminal settings.

[Neil at CASoftware]

Hi Jim,

 

PQN (or PQ – both work in this case) dictates the type of VOC record is a PROC.

 

T stands for Terminal

 

C after the T means clear screen (you could also use “T (-1)”)

 

Regards,

 

Neil.

1) PQN is the opening line of a Proc file. In Proc the "T" command outputs to "display", and the "C" switch tells it to issue a "clearscreen".

2) To get an understanding of Pick (or jBASE) go to www.jes.com, and look for Jonathan Sisk's Pick book.


Background History of Proc / Comparison with Paragraphs
------------------------------------------------------------------------------------
Universe, (and jBASE) is based on the Pick system, uses Paragraphs to create batch files.
Paragraphs start with a PA on line 1 and take the form of normal command line statements.

eg
PA
LIST FILE BY FIELD FIELD1 FIELD2

Before paragraphs existed there was another batch language, called Proc (for Procedural Language). Procs start with PQ (or PQN) in line 1. Because Universe was designed to be able to cater for every type of Pick system that would want to upgrade into it, it also caters for Procs (backward compatible)

Proc worked a bit like Assembler, in that its input and output was done using buffers. Commands in Proc had to be loaded onto a stack and then executed.

eg
PQ
HLIST FILE BY FIELD FIELD1 FIELD2
P

where H loads the statement onto the stack, and P processes it.

In proc the command to display something on screen, a bit like a java println(), is T and the switch to clear the output is a capital C, so
T C outputs a "clear screen" to the display...
