Code:
*----------------------------------------------------------------------
* N Overton : Created ( T/Code ZTUD)
*
* Dynamic table export / import facility.
*
* Restrictions - Table definition MUST exist on target
* system for import.
* - Entire table is exported / imported
* - Must be WIN95/98 WIN-NT long filenames
*----------------------------------------------------------------------
* TEXTS
*
* List Header...: For SAP Table: &1............................
*
* Column Heading: | Function Status(48 spaces)# Records |
*
* Selection Texts: PATH Folder Path for file
* P_CLEAR Delete Existing Records
* P_EXP Export to PC File
* P_IMP Import from PC File
* TABNAME SAP table name
*
* Text Symbols: B00 Dynamic Import/Export of SAP data
* B01 SAP Table Name
* B02 Program Function
* B03 Folder For Data File
* B04 Existing Records Deletion Selection
* ER2 File not found. Please check.

*----------------------------------------------------------------------
* This program once created will allow you to download or upload table
* data from any SAP table. It has the functionality to allow you to
* select whether data should be appended or original data cleaed before
* inserting new data.
* This is very useful when attempting to transfer data from one client
* to another
