8.3 Prompt Prefix

If a unit system is specified with the --units option, the selected system’s name is prepended to the ‘You have:’ prompt as a reminder, e.g.,

(Gaussian) You have: stC
           You want:
        Definition: statcoulomb = sqrt(dyne) cm = 1 sqrt_cm^3 sqrt_g / s

You can suppressed the prefix by including a line

!prompt

with no argument in a site or personal units data file. The prompt can be conditionally suppressed by including such a line within ‘!var’ ... ‘!endvar’ constructs, e.g.,

!var UNITS_SYSTEM gaussian gauss
!prompt
!endvar

This might be appropriate if you normally use Gaussian units and find the prefix distracting but want to be reminded when you have selected a different CGS system.
