Check if VISUAL is set before checking EDITOR #7

VISUAL, aka screen-oriented should be checked before EDITOR, aka line-oriented, editor - these are usually vi(1) and ed(1) respectively.

BTW, neither is set, please consider usign vi(1) :^)

In C and in Shell, this is most commonly expressed as:

${VISUAL:-${EDITOR:-vi}}
