SYNTAX of SIC commands
The SIC syntax is the following :
[LANG\]COMM [Arg1 [Arg2 [...]]] [/OPT1 [p1 [...]] [/OPT2 [...]]
where  indicates optional fields.
Language, command and options can be abbreviated. The language field
(LANG\) is optional but may help resolve ambiguities.
First, the line is stripped of duplicate separators (spaces or tabs).
Character strings (entities included between double quotes) are not af-
fected by this formatting.
Then symbols (entities included between simple quotes, plus the lan-
guage-command field) and tokens (macros parameters 1 2 etc...) are
translated, even within character strings.
Finally, the line is analysed for ambiguities and the language, command
and option names are expanded. An option is a word beginning by a slash
(e.g. /OPT1 is an option in the above example).
All arguments can be character or mathematical variables or expressions,
depending on the type required by the program. Character expressions can
be concatenated with implicit formatting of variables and mathematical
expressions, such as in
"The real number PI is equal to "'ACOS(-1.0)'
Variable and expressions are not evaluated during the parsing, but only
during the execution. Character variables must be included between
quotes for translation, e.g.
DEFINE CHARACTER C*6
LET C 3.14159
DEFINE REAL A
LET A 'C'/PI
A = 0.9999705
