- More trying to grok FORMAT, ~A padding control now.
Now I'm trying to understand the rationale behind the prefixparameters to the ~A (and ~S) FORMAT directives. I get *how* it worksbut I'm having a hard time figuring out what actual problem thecombination of mincol, colinc, and minpad solves. As in, some kind ofproblem statement of the...
