push_str_to_expr
Declaration:
void
push_str_to_expr
(EStackIndex
i
)
Category(ies):
Strings
Description:
Tokenizes and “executes” a string. This routine uses
push_parse_text
to
convert the string to externally tokenized form. Then, it applies
push_simplify_statements
to produce a fully simplified result.
Inputs:
i
— Indexes the tokenized form of a string.
Outputs:
If tokenization and execution of the string produces a result, it is pushed
onto the estack. If this process does not produce a result, then no value is
pushed.
Assumptions:
None
Side Effects:
May cause expression stack to grow or heap compression. May throw a
variety of errors associated with tokenization of the string or simplification
of the resulting form.
Availability:
On AMS 1.05 and higher.
