Using COM to access Excel through Fujitsu COBOL (inc. POWER COBOL)

Cobol Code Examples

Using COM to access Excel through Fujitsu COBOL (inc. POWER COBOL)

by  fredericofonseca  Posted    (Edited  )
The code below opens Excel on a separate process. It is not an embedded control.

It can be used from both NetCOBOL and POWERCOBOL.
For an initial test it is better if debugger is used to step through the code. Alternativelly place an accept before the "INVOKE OBJ-WBK "Close"." so that a result can be seen


Code: 
 add to repository
           CLASS COM-EXCEPTION AS "*COM-EXCEPTION"
           CLASS COM AS "*COM".

Code: 
 add to scriplets
