Re: How are you calculating 64 bit (was Processor MHz)

That reminded me of this gem from midrange computing<rip>

There also was a help uim screen, but I could not find the source (looking
for tapes...)
Here is part of the Rexx reference
http://publib.boulder.ibm.com/cgi-bin/bookmgr/BOOKS/qbkauv00/4.3

some of the neat built in functions:
d2x() is the REXX function to convert Decimal to heXdecimal.  The
data conversions available in the AS400 implementation of REXX are:
b2x()  binary    to hex
x2b()  hex       to binary
c2d()  character to decimal     (EBCDIC)
d2c()  decimal   to character   (EBCDIC)
c2x()  character to hex         (EBCDIC)
x2c()  hex       to character   (EBCDIC)
d2x()  decimal   to hex
x2d()  hex       to decimal
Mixed conversion functions are also supported.  For example, to
multiply hexdecimal 8F times decimal 19 and receive the answer in
hexdecimal format, enter the following:
XCALC 'd2x(x2d(8F) * 19)'
which will return the completion message:
d2x(x2d(8F) * 19) = A9D
