The application was written to run under windows. I suppose that it runs under any version of windows. It uses basic constructions and commands of Lazarus.
This application can be used under Lazarus modified LGPL and MPL, this allows making commercial projects that use this code but NO WARANTY, you are the only responsable if this code doesn't work or causes any problems to your computer. (I have doubts about this mr. Snijders)
You can download zip with windows executable and source or just a source zip from the Lazarus CCR sourceforge download area.
To use the program simply run it. In the first screen click the left screen button to go to the next screen(The idea is to implement new functions in this screen in the future). In the second screen you must inform the name of a partitioned data set existing in the mainframe disks. This data set will be used as input or output of the transmissions. You will inform the type of emulator you will use and the direction of the transmission. You can go to the next screen, clean the fields of the current screen or go to one level above. Depending upon the selection you do the processing goes to one of two screens:
In this screen, when you click the first button on the top of the screen, you will receive a dialog for select the file(s) you want to transmit. You can click this button more than once and select another files in another directories. You can select files in the list and exclude them with enter or delete keys. When you click the “confirm” button the program shows a dialog where you must inform the name of the file where you want the program to write the output of its processing(it will be the command that the emulator will use). You can clean the screen via “clean” button or exit and go to one level above via “exit” button.
In this screen you'll inform a name of a text file that will contain the list of file names that you want to download from the mainframe(these files must be recorded in the partitioned data set mentioned in the second screen above). Next you will inform the file extension the downloaded files must be recorded in the destination hard disk. Next you will inform the directory where the downloaded files will be written in the destination hard disk. And, finally you will inform the path and the name of the file where the command to the emulator will be written. When you click “confirm” the command is generated and written in the file you have informed early in this screen. You can clean the screen via “clean” button or exit and go to one level above via “exit” button.
These tool permits us a huge work economy in massive transmitions to and from the IBM mainframes we use. I work in a company that make migration from old databases to IBM DB2.
