CSTR 54 is short and a first read will get you a long way in getting the

.de define a macro
.ie start an if-else
.el the else part
.nr set a number register
.sp add vertical space or move vertically to a place
.if an if-else with no .el :-)
.ll set the line length
\nx the value of number register x
