  • Trailing % in "write" output

    From Sidney Reilley@21:1/5 to All on Mon Oct 25 07:56:33 2021
    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?

    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.

    [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!!

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