>From the EUPHORIA Reference Manual:
value
Syntax: include get.e
s = value(st)
Description: Read the string representation of a Euphoria object, and
compute the value of that object. A 2-element sequence, {error_status,
value} is actually returned, where error_status can be one of:
GET_SUCCESS -- a valid object representation was found
GET_EOF -- end of string reached too soon
GET_FAIL -- syntax is wrong
Comments: This works the same as get(), but it reads from a string that you
supply, rather than from a file or device.
After reading one valid representation of a Euphoria object, value() will
stop reading and ignore any additional characters in the string. For
example, "36" and "36P" will both give you {GET_SUCCESS, 36}.
Example 1:
s = value("12345"}
-- s is {GET_SUCCESS, 12345}
Example 2:
s = value("{0, 1, -99.9}")
-- s is {GET_SUCCESS, {0, 1, -99.9}}
Example 3:
s = value("+++")
-- s is {GET_FAIL, 0}
2. RE: command_line() - convert a sequence to an atom value?
Euman,
The problem, I think, is that he's got a sequence and needs the value it
represents. How would you poke the value of the sequence into the memory
address without FIRST getting the value of the sequence? And if you have to
do that first, why poke the value into memory?
