Script Variable in use another TestCase

Suppose there are two test Case: TestCase_A & TestCase_B
First Step:
Now i want to call TestCase_A and store some value in script variable for example script_VarA

Second Step:
Now i want to call TestCase_B and want to use script_VarA here as a data of desired variable

Note: without Global Variable

The easiest way is GlobalVariable; but you do not like it.

Then you have to try some twists.

  1. TestCase_A calls TestCase_B using callTestCase. The caller TestCase_A can pass whatever parameters to the callee TestCase_B.

  2. TestCase_A saves info into a local file; TestCase_B reads the file. You can chose any format you like.

thanks for replying let me do this
