Re: [jed-users] using _for [was: Dired fails on directory or file names with spaces?]

[Manfred Hanke <Manfred.Hanke@xxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hi Tom,

just briefly about using _for:

>    variable i;
>    for (i = 0; i < 8; i++) {
>        skip_chars ("^ \t");
>        skip_white ();
>    }

should translate to:

>    variable i;
>    _for i (0, 7, 1) {
>        skip_chars ("^ \t");
>        skip_white ();
>    }

or since S-Lang version pre2.3.0-75:

>    variable i;
>    _for i (0, 7) {
>        skip_chars ("^ \t");
>        skip_white ();
>    }

or even more concise using loop:

>    loop(8) {
>        skip_chars ("^ \t");
>        skip_white ();
>    }

Cheers,

Manfred
