Uh, no. Strings are passed by @address, and the only legal way to
put things in a @(x, y, z...) container is if x and y and z are simple
8-bit constants.
If you want to make an array or structure of pointers to various
things you can do that, e.g.,
DECLARE
plist (100) POINTER;
...
plist(0) = @word1;
plist(1) = @realval;
plist(2) = @string1;
plist(3) = NIL;
CALL printf(@('W1 = %d, R1 = %f, S1 = %s', 0DH, 0AH, 0), @plist);
you could do it, provided someone wrote a printf-style interpreter that
could deal with it (you don't get one with PL/M).
Someone put together a PL/M interface with the iC-86 1.0 (== awful Mark
Williams C) RTL but it didn't strike me as very usable when I tried
it out.
