The command has little utility in interactive mode, since each time a command is typed and ''[[manual:chapter6:operators:cmd_ovr_xeq|XEQ]]''ted a snapshot of the stack is pushed on the Undo stack, altering the position of the intended snapshot. </callout> <callout type="danger" icon="true" title="Compatibility"> ---- This command is new in newRPL and does not exist in userRPL. </callout> <callout type="info" icon="true" title="Usage"> ---- The following program <code> « CLEAR 123 456 789 STKPUSH CLEAR "ABC" STKPUSH CLEAR 2 STKDEPTH » </code> will push the number ''3'' on the stack, since the snapshot on level 2 of the Undo stack has 3 elements in it. </callout> <callout color="darkgray" icon="fa fa-hand-o-right" title="Related Commands"> ---- {{page>manual:chapter6:stack&nofooter&noeditbtn&inline}} </callout> manual/chapter6/stack/cmd_stkdepth.txt Last modified: 2019/10/22 15:22by jojo1973
