I want to write a script such that if a particular condition is true move ahead and if false then move back to a particular label in the script. how to do that. please help.

Hi, Please share an example or sample data.

JSL does not have a GOTO statement.  You can do what you want with a WHILE loop, CONTINUE and BREAK.

An example of what you want to do would be helpful.

does it mean the jmp script has to be ran from beginning to end? Not like other language can skip few blocks/lines or go back to certain places prior to if clause?

As @pmroz points out there are many Conditional functions that can be used to control the flow of execution of a program.

If you can post an example of the problem you're trying to solve with GOTO perhaps we can show you how to tackle it.

This is what i did and it works

a = 0;
tableExpr = Expr(  ) ;
If( a >= 1, //Condition
      Print( "Condition is true." )  //Then
,
      tableExpr  //Else
);

If condition is true then proceed else it will execute set of expressions defined earlier in the script.

I guess you dont want to wrap entire jsl code in if or while condition. instead whenever exception occurs it should skip a block. well, since no goto exist in jsl, if you work through function here is a work around. use a dummy for loop and conditional break inside a function. 

for(i=1,i<=1,i++,
  bar=12;
  break();
  bar=15;
);
show(bar);
