Ok folks this is a real stupid problem. I have a (don't laugh, I'm a poor broke college student) tandy 1000sx it is IBM compatible (suprise!) and run quick C ver 2.5 academic ver. (only $45 I told you I was cheap) this peice of sh-- will not allow me to write the OR symbol "|" it is on key 4 on the numeric key pad. I tried all different combinations of numlock and shift. it will just move the cursor or highlight the text. I'm tired of Demorgan's law (a | b= !(a & b)) isnt there a way to get around I read somewhere that C has taken into consideration that some machines do not have all the funky symbols and there are ways to get around. help me please

If it is IBM compatible, you should be able to get that symbol by holding the ALT key and typing the number 124 (the ASCII value for a | symbol), then releasing the ALT key.

The problem is with your editor. The only way it could be _failing_ to get the vertical bar (and the circumflex "^", and whatever else is on the Tandy number pad) is if it is bypassing the normal terminal input and reading the key codes itself. Try using the arrow keys (shifted and unshifted), sometimes those are interpreted as the missing keys (vterm does that on Tandys). If all else fails, write a code to convert @ to | and write all your other codes using @. J. Giles

If your compiler accepts trigraph sequences as defined by K&RII,
then,
??!
is equivalent to
|
which brings up the question: what if I want to use the
sequence "??!" within a string?

According to The_Waite_Group's_Essential_Guide_to_ANSI_C, the trigraph sequence to represent | is ??!. I haven't tried using them myself (and can't at the moment,, or I'd check), but I'd expect the trigraphs to work in 2.5, since it was released after the ANSI standard.

"?! You don't need to be!\n"); That's also useful for terminating hex escapes. -- Should you ever intend to dull the wits of a young man and to incapacitate his brains for any kind of thought whatever, then you cannot do better than give him Hegel to read. -- Schopenhauer.

Various posters say:
>) I'm tired of Demorgan's law (a | b= !(a & b)) isnt there a way to get around
btw, isn't demorgan's law a|b = !(!a & !b)?
In this case, it's: a|b == ~(~a & ~b) and a||b == !(!a && !b).
Remember that |, &, and ~ are bitwise operators, while ||, &&, and !
are logical operators.

Yeah, I'm sick of the law of excluded middle, Planck's constant, the speed of light, the law of comparative advantage, and Heisenberg's uncertainty principle. Dale, was this for real? First this jerk announces that he's tired of DeMorgan's law and then gets it wrong. I'm tired of working with people like him (and trying to teach C to students who cannot program in Cobol.)
