Reducing the number of programs on the call stack can have a
performance benefit. When a
Call (CALL) command is used,
the program called returns control to the program containing the
Call
(CALL) command. When a
Transfer Control (TFRCTL) command
is used, control returns to the first program in the call stack. The first
program then initiates the next sequential instruction following the
Call
(CALL) command.
Note: The Transfer Control (TFRCTL) command
is not valid in ILE CL procedures.
