CVLLIB - A Library of Useful RT11 Routines [Release 4] CVLLIB is a (personal) general purpose library for the RT11 Macro, Fortran or C programmer. Routines cover facilities such as reading and writing decimal (up to triple precision) and octal and hexadecimal (up to double precision) integers, money format (double or triple precision), dates and times, filenames and Radix50 formats. Numerous convenience routines are included. Multiple precision arithmetic routines are included, none of which requires an EIS or FIS. Real (floating point) routines are included, but these require either a KEV11 (FIS) or a floating-point hardware unit (FPU). Release 4 contains the C portion of CVLLIB, as well as the previously distributed Macro, Fortran and Real number sections of CVLLIB. Bugs have been fixed; unsigned decimal writing has been added (WDT is now WDST), and PSECT CVLLIB has been used for all CVLLIB routines.
