Command Reference: `or`

Returns true or false depending on whether one code-block out of multiple ones supplied is successful or unsuccessful.

Returns a boolean results (true or false) depending on whether any of the code-blocks included as parameters are successful or not.

or: { code-block } { code-block } -> <stdout>

!or: { code-block } { code-block } -> <stdout>

or supports as many or as few code-blocks as you wish.

if { or { = 1+1==2 } { = 2+2==5 } { = 3+3==6 } } then {
    out: At least one of those equations are correct
}

or does not set the exit number on failure so it is safe to use inside a try or trypipe block.

If or is prefixed by a bang (!or) then it returns true when one or more code-blocks are unsuccessful (ie the opposite of or).

or only executes code-blocks up until one of the code-blocks is successful then it exits the function and returns true.
!or only executes code-blocks while the code-blocks are successful. Once one is unsuccessful !or exits and returns true (ie it nots every code-block).
