read — File Read
read is a function that allows you to read in variables from a
file. The string argument specifies the file to read from. All the
variables that are stored in the file are read in, overwriting any
existing variables with the same name. The file is closed after it
has been read from. This function returns 1 is the read succeeds.
The format of the file is quite specific, and it is intended that this
function be used with the write function. Trying to create a
file that can be read from is fraught with danger. If it is
essential, I suggest using write to create one similar, and
then editing as little as necessary.
