(format t "~C ~D ???" var1)
Who can give a tip, How/Where in the all power Hyperspec can we find a list of the control string?
Things like this, when it’s going to find some hints about the Lisp control string of the format, the Hyperspec always HYPER me.
I tried: C-c C-d h format, C-c C-d h formatter, C-c C-d h tilds … They all lost me.
Try C-cC-d~(i.e.,
common-lisp-hyperspec-format). Tab will show a summary. In case you forgot, it’s always reachable from C-hm(describe-mode).
