ENTERLEVEL

System variable:  ENTERLEVEL  
Length/precision:  2.0  
Description:  
The system variable named ENTERLEVEL is a two-digit numeric variable whose value equals the relative subprogram level of the program currently executing. 
If ENTERLEVEL equals zero, the current program is not a subprogram (i.e., it was RUN, not ENTERed). 

Values greater than zero equal the number of ENTER operations used to execute the current program. 
For example, a value of 5 means than 5 ENTER operations were executed to run the current program (i.e., the current program is 5 subprogram levels deep). 
See ENTER and EXIT for more information on subprograms. 

When a program is ENTER'd the system variable RUNSTATE is set to 6.
