STL Program Code Assistance

rlh_Ilpea Posts: 4 Rating: (0)	I have a piece of a STL program listing below that is used in a program block - I was wanting to see if someone could assist with what the code actually does - LMW 2 L DB20.DBW8 >=I = #temp1 Thanks,

Attached you find a list with stl commands, hope it helps. Regards, Marcjan Attachment STL-cheat-sheet-by-alphabet.pdf (117 Downloads)
