Those functions work with equation objects. For example, let's say you have an equation stored in a variable named "EQ"; say, XSTR "A*X^2+B*X+C" PARSE STO "EQ".
And you have a program like LBL "PG" MVAR "X" MVAR "A" MVAR "B" MVAR "C" RCL "X" X^2 RCL* "A" RCL "X" RCL* "B" + RCL+ "C" END.

Then:
EVALN "EQ" is equivalent to XEQ "PG"
EQNVAR "EQ" is equivalent to PGMVAR "PG"
EQNMENU "EQ" is equivalent to VARMENU "PG"
EQNMNU1 "EQ" is equivalent to VARMNU1 "PG"

Note that an equation object stored in a variable named "EQ" is not the same as an equation in EQN mode that is named EQ. Those two things live in completely separate name spaces.
