# Final Release Note The [ZSHOW Information Code](https://docs.yottadb.com/ProgrammersGuide/commands.html#zshow-information-codes) "V" can take an optional additional \<intexp> parameter to specify the stack level (corresponding to [$STACK](https://docs.yottadb.com/ProgrammersGuide/isv.html#stack)) for which the command is to output local variables. A value of -1 is an alias for $STACK. A negative value for the parameter, or one greater than the current value of $STACK raises a [STACKRANGE](https://docs.yottadb.com/MessageRecovery/errors.html#stackrange) error. ``` YDB>zshow "v"::2 a="The quick brown fox" c="jumps over the lazy dog" YDB>zshow "v" a=1 b=2 c="jumps over the lazy dog" YDB>set n=2 zshow "v":d:n zwrite d d("V",1)="a=""The quick brown fox""" d("V",2)="c=""jumps over the lazy dog""" YDB> ``` If the information codes of a ZSHOW command with a stack specification do not include "V", the stack specification is silently ignored. Other ZSHOW information codes ignore the stack specification, e.g., ZSHOW "vs"::2 (assuming $STACK>2) displays the local variables for $STACK level 2, as well as the current M stack. [#873] # Description Currently, there is no way in YottaDB to display the M variables at a specific stack level. A few of our users raised this as an issue. An idea is to perhaps enhance `ZSHOW "V"` to be able to display the stack at a specific `$STACK` level. ZSHOW takes two colon parameters right now; perhaps it can be changed to take a third colon parameter of a `$STACK`, like this: ``` ZSHOW "V":^DEBUG:5 ``` # Draft Release Note The [ZSHOW Information Code](https://docs.yottadb.com/ProgrammersGuide/commands.html#zshow-information-codes) "V" can take an optional additional \<intexp> parameter to specify the stack level (corresponding to [$STACK](https://docs.yottadb.com/ProgrammersGuide/isv.html#stack)) for which the command is to output local variables.
