LET Free_Syntax
The LET command may be omitted if no option is present, and if the
SIC syntax is set to FREE. In this case, the = sign is mandatory. In
FIXED syntax, the LET command is compulsory, but the = sign optional. In
FREE syntax, commands lines like
A[I,J] = SIN((2*I+J)/PI)
where A is a known variable, are recognized as assignement and automati-
cally expanded to the equivalent FIXED syntax
LET A[I,J] SIN((2*I+J)/PI)
In case of conflict between a variable name and a (complete) command
name, an error message is issued. Free syntax cannot be used for the
LET /WHERE command. Command SIC SYNTAX [Free|Fixed] can be used to tog-
gle between Fixed and Free syntax if needed.
