The PARSECELLMESSAGE command (aka PARSECELLMSG) facilitates parsing cell messages sent by listview controls. The arguments are the names of variables with the following properties:
- the variable whose name is stored in srcvar contains the input to
PARSECELLMESSAGE, i.e. the argument passed to the message nameCELLEDITEDorCELLEDITEDBACKTAB, respectively
- the variables whose names are stored in the remaining arguments are where the parsed output of the
PARSECELLMESSAGEcommand will be stored. Their meaning is as follows:
+* the variable whose name is stored in itemvar will be set to the number of the dialog item the message is referring to;
- the variables whose names are stored in rowvar and colvar, respectively, will be set to the row and the column the cell message is referring to;
- the variables whose names are stored in newlenvar and newvalvar will be set to the length of the *new* value of the respective cell, and to this value itself, respectively; and, finally,
- - the variables whose names are stored in oldlenvar and oldvalvar will be set to the length of the old value of the respective cell (i.e. the value it contained *before* the edit reported by the message has taken place)
