providex, mas 90 & mas 200
Erwin Herbst [917.407.7080] has developed an elegant and flexible way to print barcodes on Zebra printers. While Zebra printers come bundled with labeling software there are times when you want more control over printing Code 128, UPC, Code 39, etc. on Zebra printers.
Erwin does it using ProvideX, the very same language as MAS 90 and MAS 200. His program reads the data from MAS 90 and MAS 200 complete with lookup capabilities.

It prints labels 1-up or 3-up and can easily be modified.
One big advantage of using this particular program is that it is written in native MAS 90 and it does not utilize a MAS 90 "user". Contact Erwin Herbst to order a copy.
