Dear Sergiy,

I'm using Stata 12.1, and it seems to me that the limit might be 254 characters:

forvalues i = 1/265 {
    display as res `i'
    local x : display _dup(`i') "x"
    display "{stata `x'}"
}

I'm not sure where that limit comes from. A workaround might be to put
the command in a do-file or program, and then have the {stata}
directive execute the do-file/program rather than the command. For
example, in -help graph pie-, the "click to run" links don't run the
actual long commands, but instead run a program that contains the
commands (-gr_example2-).

Best,
Matt
