Context keyword service – PB Docs 2021

To access environment variables:

1. Declare an instance or global variable of type ContextKeyword.
   Also declare an unbounded array of type String to contain returned
   values:

   PowerBuilder

   ContextKeyword icxk_base String is_values[]

   1 2	ContextKeyword  icxk_base String   is_values[]

2. Create the context information service by calling the
   GetContextService function:

   PowerBuilder

   this.GetContextService("Keyword", icxk_base)

   1	this.GetContextService("Keyword", icxk_base)

3. Call the GetContextKeywords function to access the environment
   variable you want. This example calls the
   GetContextKeywords function to determine the current application
   Path:

   PowerBuilder

   icxk_base.GetContextKeywords("Path", is_values)

   1	icxk_base.GetContextKeywords("Path", is_values)

4. Extract values from the returned array as necessary. When
   accessing environment variables, the array should always have a
   single element:

   PowerBuilder

   MessageBox("Path", "Path is: " + is_values[1])

   1	MessageBox("Path", "Path is: " + is_values[1])
