moved on to work with Burroughs equipment. This hardware was strongly oriented
around a stack. This influenced the further development of Forth. Implementations were
written in BALGOL, COBOL and SBOL (the Burroughs Systems Programming
Language). These provided manipulation words for the stack: DROP, DUP, SWAP, etc.
which are still found in modern Forth systems. The first true Forth system which
resembled what we now perceive as Forth was then created by Moore on an IBM 1130.
The word size of this machine limited the users to having names of not more than five
characters. Had it not been for this IBM limitation the name `Forth' would have been
`Fourth' - standing for Fourth Generation Language."
Could someone explain better to me what the boldened words/phrases mean in this context? Is it anything like:
Code: Select all
IF [STATEMENT]
{
IF [STATEMENT]
{
}
ELSE IF [STATEMENT]
{
IF [STATEMENT]
{
}
}
}
