Hi All,

How to know what data type is passed to the amper variables.

This link provides lots of info about creating and using ampersand variables.

nsk,

As a rule, &variables contain characters.
These characters can be either numbers or alphas.
Dialog Manager will treat any &variable containing an integer (4-byte binary), or a decimal (dbl-precision floating point) as a number. Anything else will be considered an alpha and you can test this with the ".TYPE" postfix function.

See (and run) the following examples:
-SET &A='123';
-TYPE &A.TYPE
-SET &A='ABC';
-TYPE &A.TYPE
-SET &A='1234567890';
-TYPE &A.TYPE
-SET &A='1234567890123';
-TYPE &A.TYPE
-SET &A='12345678.123456789';
-TYPE &A.TYPE
-SET &A='123456789012345.12345';
-TYPE &A.TYPE
