Macro levels

Each macro operates on a separate and unique level. A person at the keyboard always operates at level 0. If that person starts a macro, it operates at level 1; the macro started by a level-1 macro operates at level 2, and so on. The level is the degree of macro nesting. Edit macros are primary commands; thus, nested macros are started by prefixing them with ISREDIT.

A macro can determine its own level with this assignment statement:

ISREDIT (varname) = MACRO_LEVEL

The current level number is stored in the specified variable. ISPF supports up to 255 levels of macro nesting.
