Next: Spelling of keywords Up: Command Previous: Command   Index


Each command instructs SWAN to carry out a certain action which SWAN executes before it reads the next command. A command must always start with a keyword (which is also the name of the command) which indicates the primary function of that command; see list in Section 4.1). A simple command may appear in its command scheme as:

  KEYword data
A command may contain more than one keyword (which refines the instructions to SWAN), e.g.,
  KEY1word KEY2word data
where KEY2word is the second keyword.
