1.4.9 RDMLX Benefits

RDMLX is an extension of LANSA's RDML. RDMLX development is done using Visual LANSA. In addition to supporting all LANSA RDML features, RDMLX-enabled partitions support RDMLX language features hich include:

• use of intrinsic field methods

• use of function libraries

• use of expressions in many parameters and properties

• enhanced RDMLX command support such as assignment statements

• simplification of RDML statements due to the removal of quotes.

For example, an intrinsic field method can be used instead of using a Built-In Function to convert a number to a string.  A numeric field such as #SALARY can be referenced as #SALARY.asString as in this example:

#PHBN_1.Left := #PHBN_2.Right + 10

 

#FullAddress := RightTrim(#Address1) + ' ' + RightTrim(#Address2) + ' ' + RightTrim(#Address3)

 

SET #Com_Owner Left(#Com_Owner.Left + 2) Top(#Com_Owner.Top + 2)

 

IF ((#QUANTITY *LT 10) *AND (#MEASURE *GT 10.5))

 

IF (#PHBN_2.Caption.Substring( 1, 1 ) = 'A')

 

#STD_NUM := Length(Trim(#Com_Owner.StringMethod(#Address1 #Address2)))

 

DOUNTIL (#I >= 11)

These language features may only be used in RDMLX Objects.

In order for an existing component to use these language features, the partition and components must be Enabled for RDMLX.
