Disadvantages

• Some issues with syntax like uppercase for keywords.

• Variables are persistent and global. Memory management thus is an issue.

• It has a very monolithic design that is low-level optimizations to the code is not possible.

• I/O from files was not implemented. Thus, it could not be used for reading and writing from files.

• Because of the way variables were implemented it was not possible to implement temporary or session specific variables without exclusively deleting them.
