Scripting: How to include an If-Then statement in a script intended to write text to a file?
Here is a line I wish implemented if the value of a token is under 100:
out.write( dataRecord.get( "RANK_PINunder100" ) + "\t" );
Here is a line I wish implemented if the value of a token is 100 or more:
out.write( dataRecord.get( "RANK_PIN100Plus" ) + "\t" );
One of these datarecord field values will be null and the other will have a value. RANK_PINunder100 field holds values 1-99 and RANK_PIN100Plus holds values 100 and over.
I would like to declare MyLimitedScopeScriptVar in a script, examine the 2 token values (one will be null) and assign the NON-NULL value to MyLimitedScopeScriptVar.
How do I script something like this...
IF NOT ISNULL(dataRecord.get( "RANK_PINunder100" )) THEN WildCardSessionVar = dataRecord.get( "RANK_PINunder100" ) ELSE WildCardSessionVar = dataRecord.get( "RANK_PIN100Plus" ) ENDIF ????
Then I could invoke something like this...
out.write( MyLimitedScopeScriptVar ) + "\t" );
UNCERTAINTIES:
CAN A SESSION VARIABLE HOLD NULL? IN VB, THAT REQUIRES A SPECIAL VARTYPE.
CAN A SESSION VARIABLE BE DIRECTLY REFERENCED IN A SCRIPT?
CAN A VARIABLE BE DECLARED IN A SCRIPT AND ASSIGNED A VALUE? HOW?
CAN I SAFELY ASSUME THE "\t" A TAB DELIMITER?
One more thing... Can I declare a variable for use in a script that has scope limited to the script itself. In other words, after the script is processed, variable vanishes and associated memory is freed? Would like to use a script var rather than a session var.
Thanks in advance. MrFizz [at] FizzGiz [dot] com.
I could explain all of these
I could explain all of these things to you but I think you're making things a lot harder than they have to be.
If you have 2 ways the data can be shown like this:
Just make one pattern to match both like this:
Then you just don't write out the "JUNK".
If you want to check that a value is not null, it is:
if (dataRecord.get("RANK_PIN")!=null)
If you set a session variable to null you effectively unset it.

Mike,
To finish with your UNCERTAINTIES:
CAN A SESSION VARIABLE HOLD NULL? IN VB, THAT REQUIRES A SPECIAL VARTYPE.
Yes (no special VARTYPE required):
session.setVariable("MyVar",null);CAN A SESSION VARIABLE BE DIRECTLY REFERENCED IN A SCRIPT?
Yes:
session.getVariable("MyVar");CAN A VARIABLE BE DECLARED IN A SCRIPT AND ASSIGNED A VALUE? HOW?
Yes:
session.getVariable("MyVar","some value here");CAN I SAFELY ASSUME THE "\t" A TAB DELIMITER?
Yes:
session.log("This is a tab: \t");One more thing... Can I declare a variable for use in a script that has scope limited to the script itself. In other words, after the script is processed, variable vanishes and associated memory is freed? Would like to use a script var rather than a session var.
Yes:
myVar = "some value here";The best way to answers many of these questions is to test them and see. If you're not sure how to, say, set a session variables you can always reference the API.
