The zmbq solution is good, but cannot be used in all situations, such as inside a block of code like a FOR DO(...) loop. An alternative is to use an indicator variable. Initialize it to be undefined, and then define it only if any one of the OR condition, One way to implement logical-or is to use multiple conditionals that goto the same label. if %1 == 1 goto :cond if %1 == 2 goto :cond goto :skip :cond someCommand :skip. To test for set membership, you could use a for-loop: for %%i in (1 2 3 4 ... 20) do

大家好,我有一個BAT的問題,. 在BAT內包含有FOR, 在FOR之內再有IF和SET. 當運行後在IF 內不能SET到一個參數(黃色字內). 在正常情況下運行IF 後SET 可以修改參數. 同樣的做法但不是用SET, (對上一行藍色是可以有效運行的). 但放於FOR之內就失效了, 請問各位知道原因嗎? 謝謝. SET PCNAME=PCLIST.TXT https://social.technet.microso [Solved] Batch 'and', 'or', ect help - Computing.Net
