SCRIPT VARIABLE and SCREEN TEXT COLLISION

[Niroj@Work]

Many times the text coming from a screen may be same as the variable name used inside the script. e.g.

// A variable storing a value
Let>TEST=123

// TEST a string coming from the screen; we don't have any control over it..!
Let>var=TEST

// Now if I want to display only TEST not 123 What I need to do?

I tried as below:
Let>VAREXPLICIT=1
Mdl>%var%
Let>VAREXPLICIT=0

Hi Niroj@Work,

Your easiest solution might be to use very uncommon variable names... so uncommon that there is almost no chance that the variable name itself will ever be encountered in any text you might assign to it.

Check out the following post for a detailed description of what is going on...

Hi,

The problem is with the location of the varexplicits. Try this:

Code: Select all

Let>VAREXPLICIT=1 
// A variable storing a value 
Let>TEST=123 

// TEST a string coming from the screen; we don't have any control over it..! 
Let>var=TEST
//back to default value for varexplicit, if you wish. 
Let>VAREXPLICIT=0 

// Now if I want to display only TEST not 123 What I need to do? 

Note how the variable expansions work in these cases: 
Mdl>%var%
mdl>var
mdl>%TEST%
mdl>TEST
mdl>var:%var%
mdl>TEST:%TEST%
