The %fputc() function writes the character specified by character on the named output stream.
var = %fputc(character, (char*)stream)
If successful, the character is returned as a number, otherwise eof (-1) is returned.
If the character is contained in a FlashBASIC dynamic array, an explicit (char) type override must be used, otherwise a pointer would be passed to the C function.
c=’a’ n=%fputc((char)c, (char*) strm)
