NetLinx Programming Language Reference Guide
Right-to-left languages are not stored differently than left-to-right languages, they are simply rendered
differently than right to left languages.
However, note that the functions WC_LEFT_STRING and WC_RIGHT_STRING remove a number of
characters from the start and end of a string respectively. Using WC_LEFT_STRING on a right-to-left
language will return the number of right-most, i.e. first, characters you requested, not the left-most, i.e.
end, characters.
WC_LEFT_STRING returns the number of characters request from the front of the string and
WC_RIGHT_STRING return the number of characters requested from the end of the string, regardless
of the language's orientation.
Compiler Errors
The most common type of compiler errors you will encounter while programming for Unicode are
caused by not wrapping Unicode string literals in _WC, passing a WIDECHAR to a function that take a
CHAR array or passing a CHAR array to a function that takes a WIDECHAR array.
If you forget to wrap a Unicode string in _WC, expect to see the following compiler error:
On the line where the string is defined:
C10571: Converting type [string] to [WIDECHAR]
On the line where the constant or variable is used:
C10585: Dimension mismatch: [1] vs. [0] and C10533: Illegal assignment statement
If you try to pass a CHAR array to a function that expects a WIDECHAR array, expect to see the
following compiler error:
On the line where the function call is made
C10585: Dimension mismatch: [1] vs. [0] and Type mismatch in call for parameter
[WCDATA]
If you try to pass a WIDECHAR array to a function that expects a CHAR array, expect to see the
following compiler error:
On the line where the function call is made
C10585: Dimension mismatch: [1] vs. [0] and Type mismatch in call for parameter [A]
Parameter names might not match those listed above.
