Further information
1.
The parsing begins at the specified starting position and stops
as soon as an invalid character is found. This location is then stored
in the parameter
sys_endparse.
2.
The optional base argument may be used if the text is not expressed
in base 10. Valid values for this parameter is 0 and 2 to 36.
If base is zero or 16, the string may then include a '0x' prefix, and the
number will be read in base 16.
Furthermore, if the base is 0, the text will be read in base 8 if the
first character is 0 and in base 10 otherwise.
