What is the function which pulls substrings out of a string, or,
, e.g., writes out the characters in a string as a list.
Also, if this is easy to find in the manual, please tell me where.
For instance, which function 'f' will do the following.
(%i1) f("world");
(%o1) orl
or just the following.
(%i2) f("world");
(%o1) w
That is, extract the first letter of the string.
TIA,
-sen
