An equal sign prefix usually means to write instead of read. Anywhere an instruction is allowed, it may be one of these instructions, or it may be a constant value, or reading/writing a variable (see the above section about variables specific to objects), or a block instruction (see the next section for block instructions). Many instructions are state-changing instructions; these instructions are marked with ** in the summary line. Such instructions are not allowed to be used on the same turn as the IgnoreKey instruction. <function> Call a user-defined function (the name starts with a ampersand). <global> ( -- any ) Read a global variable. =<global> ( any -- ) ** Write a global variable. <label> Define a label. Labels are local to the current class. (Label names always start with a colon.) =<label> Go to a label. (Put the colon after the equal sign; this instruction, and the one below, are using a double sigil.) ,<label> Call a label as a subroutine; when it returns, comes back to here. . ( x -- ) + ( in1 in2 -- out ) Add two numbers together. - ( in1 in2 -- out ) Subtract in2 from in1. |
