Using programmed symbols for IBM 3270

Programmed Symbols (PS), an optional feature on the IBM® 3270 terminal, lets you store and access up to six character sets of 190 characters each that are user-definable and program-loadable.

After the coded graphic character sets have been loaded into the PS buffers, they can be used on a field-by-field basis by using Message Format Service (MFS).

If the PS buffers are desired and have not been loaded, they must be loaded by a VTAM® application or by some other means.
