Zugg Software :: View topic - %pop does not understand stringlists in record variables

Novice Joined: 26 Jan 2009 Posts: 32

#NEWVAR Record "" _nodef
#CALL %vartype(Record,5)
#ADDKEY Record StringList "One"
#ADDKEY Record StringList %push("Two",@Record.StringList)
#SHOW %pop(Record.StringList)

Outputs :
StringList

and clears the key in the newly created variable @Record and turns the type to stringlist.

You can workaround using something like the following (within an alias) :
#ADDKEY Mud SendOnPrompt %additem( %1, @Mud.SendOnPrompt)
#IF (@Mud.PromptWaiting) {
#SEND %item( @Mud.SendOnPrompt, 1)
#ADDKEY Mud SendOnPrompt %delnitem( @Mud.SendOnPrompt, 1)
}

That is correct and is a limitation of record variables. Record variables are meant to store *string* values and not string lists. The %pop function requires a simple variable name and does not support the "Record.StringList" syntax.

Also, any time you try to store a string list within a record variable, you are losing all of the high-speed hashing in CMUD to make string lists faster. CMUD is forced to convert your string list into a string value, then store it into the record variable, and then rebuild the string list hash table every time you access it. So in general, try to avoid storing string lists within database variables.
