[NeedsAccessToLocalsAttribute(true)] public static Usual VarPut( string cVarName, Usual uValue )
Parameters
- cVarName
- Type: String
The name of the variable you want to create. - uValue
- Type: Usual

If a field or memory variable called cVarName does not exist, a memory variable called cVarName is created.
Therefore, VarPut(), like MemVarPut(), can be used to create undeclared memory variables.
It should be used instead of a macro.

Dynamic memory variables (PUBLIC, PRIVATE, PARAMETERS) are supported in the X# language and runtime for compatibility only. In most cases the type can and should be replaced with lexically scoped variables, such as LOCALs and GLOBALs. |
Examples
This example uses VarPut() to store a value into a database field:
This example uses VarPut() to create a memory variable:
This example shows that the newly created variable is a MEMVAR:
X#
1LOCAL cFieldName 2cFieldName := "Address" 3VarPut(cFieldName, "Hollywood, Room 222")
X#
1LOCAL cHasName 2cHasName := "cPrivate" 3// Instead of &cHasName := "new", use this: 4VarPut(cHasName, "new") 5? cPrivate // new
X#
1VarPut("cVar", "hi") 2? _MEMVAR->cVar // hi
