Hello!
A complete BASIC dialect means 100% BASIC syntax.
( https://pl-wikibooks-org.translate.goog/wiki/BasicC/Operatory?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=zh-TW&_x_tr_pto=wapp )
For example, ordinary BASIC dialects don't use Let(X,Y). They use Let X=Y or X=Y. If you change the syntax of BasicC to 100% BASIC syntax, it may be more easier for you to promote this programming language. More popular.
