Noob here! Just an old tinkerer, trying to keep the grey cells
active. :-)

Using Okane's mumps implementation on a Debian-based Linux box.
Reading T.L. Wiechmann's "MUMPS Programming I Student Guide".

Testing the commands READ and WRITE.
The routine works OK, but the output always has a trailing _%_ .
Is this output buffer garbage? Do I need to flush the buffer first?
If so, how? TIA ..

Totally enjoying Mumps!!

There should not be any trailing characters.
Can you show the exact commands you are trying?

[code]
#!/usr/bin/mumps

; routine to illustrate the commands
; DO, GOTO, and QUIT
READ ; get date from the user
read !!,"First Number: ",First
if First="" quit
read !,"Second Number: ",Second
if Second="" quit
DO RESULTS
GOTO READ
RESULTS ; display the results to screen
write !?5,"Sum: ",First+Second
write !?5,"Product: ",First*Second
quit ; end of routine
[/code]

It works, but the GOTO command doesn't seem to work in my routine.
I messed up somewhere! Thx!!

The rendition of white-space is always a problem on platforms like this, so it's hard to tell, but...
In your example, all lines, except the ones with a label (READ and RESULTS), should start with a space.

Thx Ed! And they do start with a space (except for the labels) - actually 4 or 5 spaces. Would the extra whitespace matter?

Got it working! No trailing garbage in the output! WHY? God _only_
knows!

Also, I got rid of the "quit" command at the end of the routine,
and the "goto" command now works as expected. Entering a CR exits
the routine - as expected. Thanks Ed!
