Example E-7: Special SSGET Operation in TAL
Example E-7 on page E-22 demonstrates the basic buffer manipulation activities
illustrated in Figure 2-7
on page 2-26. This TAL program uses DSM Template Services
to display the contents of the buffer after each manipulation. Run the program to see
the behavior of the SSGET special operation ZSPI-TKN-NEXTCODE.
