Function prototype: Difference between revisions

=={{header|Amazing Hopper}}==

Function prototypes are included in a #PROTO declaration in the header, at the beginning of a HOPPER source file, before the functional code (MAIN :). This is enforced by the HOPPER compiler, to declare pseudo functions.

<lang Amazing Hopper>

#proto noargs /* Declare a pseudo-function with no argument */

#proto twoargs(_X_,_Y_) /* Declare a pseudo-function with two arguments */

main:

_no args

_two args (2,2)

print

exit(0)

.locals

twoargs(a,b)

{a}mulby(b)

back

// This function is as useful as an ashtray on a motorcycle:

no args:

{0}minus(0),kill

back

</lang>
