Call an Amiga Library routine. CALL is an IMMEDIATE word, which can ONLY be used in a colon definition. At compile time it will look up the calling parameters in the FD file and build the appropriate code that, at run time, will: 1) Load the correct registers in order from the stack. ( The order the arguments appear in source text is the same as listed in the AmigaDOS technical manuals, and with the ARGS command. ) 2) Load Amiga register A6 with the correct library base pointer. 3) Call the correct location, offset from the base pointer. 4) Use register D0 as a 'universal' return code, moving it to top of stack. Please note that addresses passed to the Amiga must be converted from RELATIVE to ABSOLUTE! Please see the words ABS and CALLABS for this. Please also see the chapter on Calling Amiga Library Routines for more information about CALL. Related Words: CALLVOID CALLABS AREGSABS :LIBRARY DCALL REL ABS
number: A call number is like a book's address. Each item in the library has a unique call number which you trace through the Library Catalogue http://booleweb.ucc.ie. The call number is printed on the white sticker attached to the spine of the book. See also Dewey Decimal Classification.
NUMBER - The number given to each book acquired by the Libraries. Every book has a unique call number, much like every house in a city has its own address. The first portion of the call number (one or two letters followed by a few numerals) is the "name" of the "street;’ the second portion (following the period) is the "house number." Example: PR 6023 .L47 H6 You can find the call number of a book in AUBIECat. By consulting an appropriate floor plan posted in the stacks or at any reference desk, you can then locate the book’s general "neighborhood" and go to that area to find its exact location. One caution: call numbers preceded by "f" or " folio" indicate that the book is too large to fit on the regular shelves. You should refer to a floor plan to determine where on each floor of the RBD Library these "oversized" books have been shelved.
