ST Language

The ST language is a text language with a similar grammatical structure to the C language.
Controls such as conditional judgement and repetition process written in syntaxes can be
described.
This language is suitable for programming complicated processes that cannot be easily
described by a graphic language (structured ladder language).

comment.
