               The following environment variables control the run time virtual memory 
                  		
               
 
               		
                
                  		   
                  			 
                  - MFMP 
                     			 
                  
- This must be set to 
                     				ON for assembler to execute. 
                     			 
                  
- Example: 
                     				
                     MFMP=ON 
                        				
                      
- SVC370 
                     			 
                  
- This switch is related to backward compatibility. It must always be set to MFI. 
                     			 
                  
- Example: 
                     				
                     SVC370=MFI 
                        				
                      
- MEMSIZE=<LOW>,<HIGH> 
                     			 
                  
- Maximum 370 linear address that assembler modules can address. A value of 
                     				0,7FFFFFFF addresses the bottom 2 gigabytes of 370 virtual memory 
                     			 
                  
- Example: 
                     				
                     MEMSIZE=0,7FFFFFFF 
                        				
                      
- VM370 
                     			 
                  
- Amount of memory, starting at absolute address 0, to be allocated for the use of 370 assembler modules to be loaded into.
                     Default is 3 meg below the 16 meg address line. 
                     			 
                  
- Example: 
                     				
                     VM370=3000 
                        				
                      
- AMODE370 
                     			 
                  
- Tells the assembler emulator which addressing mode to initially start in when the first assembler module is called. 
                     			 
                  
- Example: 
                     				
                     AMODE370=31
