Condition Expressions

[Krishna K Kammaje]

Hi,

I am using following expressions for a condition step. (Assume that 
&NOTIFICATION.APPROVALREQFLAG& can either be 'X' or blank)

Please let me know the difference between following two expressions in 
this case. 

1. &NOTIFICATION.APPROVALREQFLAG& EX

2. &NOTIFICATION.APPROVALREQFLAG& = 'X'

Thanks
