elseif — Defines another "if...then" condition when a "if...then" condition is false.
elseif xa R xb then
where label is in the same instrument block and is not an expression, and where R is one of the Relational operators (<, =, <=, ==, !=) (and = for convenience, see also under Conditional Values).
elseif is used inside of a block of code between the "if...then" and endif opcodes. When a "if...then" condition is false, it defines another "if...then" condition to be met. Any number of elseif statements are allowed.
Here is an example of the elseif opcode. It uses the file elseif.csd.
