HELP POP_PR_RATIOS                           John Williams, January 1986

    <boolean> -> pop_pr_ratios

The variable POP_PR_RATIOS controls the way in which *SYS_SYSPR prints
ratios. If <true>, (the default), ratios are printed like this:

    true -> pop_pr_ratios;
    6_/10 =>
    ** 3_/5

i.e. the numerator and denominator are printed, separated by '_/'.
Note this is a re-readable format.

If POP_PR_RATIOS is set <false>, then *SYS_SYSPR coerces ratios to
ddecimals before printing:

    false -> pop_pr_ratios;
    6_/10 =>
    ** 0.6

In non-mathematical applications, where precise knowledge of how a
particular numeric quantity is represented is not relevant, this format
may be preferable, since decimal point notation is often easier to
comprehend.

Formerly, POP_PR_RATIOS was a library package that re-defined the
CLASS_PRINT of the ratio key.
