Strider--NES version

[Oldmannes]

anyone know how to do the fricken wall jump... i am gonna loose my mind here.

[Kong]

It has been a couple years so my memory might be off a bit.

You have to bounce off the wall. You jump hit the wall, jump again and go the other direction and bounce off something else and land on top of the wall.

[NintendoNerds]

...It is possible to jump very high by bouncing off walls. Jump toward a wall and when you hit it, jump again in the opposite direction. It is even possible to do a series of these and climb up chimneys...

Taken from the Strider Instruction Manual

This is prety much what Kong stated, but I saw this in the manual and thought that I would add it.
