ECHOS and trailing spaces

[JohnQSmith]

Working on a solution for Scott's post. Had to make some more sample data so I wrote a quick btm.

do a = 1 to 100 (
    do b = 1 to %@random[14,20] (
        set c=%@convert[10,16,%@random[0,255]]
        iff %@len[%c]== 1 then
            echos 0%c` `
        else
            echos %c` `
        endiff
    )
    echo.
)

I've tried with a trailing space enclosed in backquotes (as in the code above) and also with a space after the %c followed by double backquotes. Neither will output spaces between the echos. In other words, I'm getting this

Instead of this

0B 02 59 F5 68 18 57 6A 48 B6 C7 E4 68 DB 3F 30
52 68 2A 45 3C 0D FB AB 12 E8 EF D9 77 49 00

4A 30 84 61 29 BF C0 4E 13 E7 BA AA E5 FA 8A 59 81 AF 6F

If I put an additional space between the ECHOS and the %c, I do get spaced output, but I want trailing spaces, not leading spaces.

Edit: Problem is in both TCC 13.04.63 and 14.00.23 for Windows XP SP3

IIRC, this has been discussed a few times and the behavior has not changed. There's no such problem with FOR.

v:\> do i=1 to 3 (echos %i` `)
123
v:\> for /l %i in (1,1,3) echos %i` `
1 2 3

This might help:

v:\> do i=1 to 3 (echos %i^k ^k)
1 2 3

do a = 1 to 100 (
    do b = 1 to %@random[14,20] (
        set c=%@convert[10,16,%@random[0,255]]
        iff %@len[%c]== 1 then
            echos 0%c` `
        else
            echos %c` `
        endiff
    )
    echo.
)

As it's in a .BTM file, I recommend that you use a proper DO loop:

@echo off
do a = 1 to 100
    do b = 1 to %@random[14,20]
        set c=%@convert[10,16,%@random[0,255]]
        iff %@len[%c]== 1 then
            echos 0%c` `
        else
            echos %c` `
        endiff
    enddo
    echo.
enddo

Using the parentheses essentially mashes the body of the loop onto a single command line -- a hack to make DO usable at the command line, not needed in a batch file. I don't fully understand the side effect that you're seeing, but I'm not at all surprised that there is a side effect.

That works. I was using the parentheses as one would use curly brackets in C or Java.
