ABlogix diagram

ABlogix.m4: The Autologix macro can draw inputs on the left but the added drawing complexity may require hand tuning with second-argument options: L puts the inputs on the left, R reverses their order, V scans the input arguments in reverse order, and offset=value displaces the array of inputs

graysurf.m4: Plotting a surface using a gray scale

ex09 diagram

ex09.m4: Illustrating the macro dimension_(linespec, offset, label, D|H|W|blank width, tic offset,<-|->). A negative second argument implies an offset to the right of the linespec direction. A label starting with " or sprintf is copied literally. If label is an s_box(...) then setting argument 4 to H, W, or D tailors the blank width to the s_box height, width, or diagonal respectively; i.e., W is equivalent to s_wd+textoffset*2
