# /STACK
```  
/STACK:reserve[,commit]  
```  
  
## Remarks  
 This option sets the size of the stack in bytes and takes arguments in decimal or C-language notation. The /STACK option applies only to an executable file.  
  
 The *reserve* argument specifies the total stack allocation in virtual memory. EDITBIN rounds up the specified value to the nearest 4 bytes.  
  
 The optional `commit` argument is subject to interpretation by the operating system. In Windows NT, Windows 95, and Windows 98, `commit` specifies the amount of physical memory to allocate at a time. Committed virtual memory causes space to be reserved in the paging file. A higher `commit` value saves time when the application needs more stack space but increases the memory requirements and possibly startup time.
