how get programs version in MQL?

[selnomeria]

for example, i want to have a condition like this;

if (ThisIsMT5) then do1(); 

else do2();

how can i automatically determine if running platform is MT5 or MT4 (mql5 or mql5) ?

This can only be done at compile time via prepocessor. The platform provides for you 2 values: __MQL5__ or __MQL4__ - only one of them will be defined.

found better way maybe:

int MT_version;
......
......
if (MT_version == NULL){

     if(StringFind(MQLInfoString(MQL_PROGRAM_PATH),   "MQL4",0 ) > -1 ||   TerminalInfoString(TERMINAL_NAME)=="MetaTrader 4" ) MT_version = 4;

     else if(StringFind(MQLInfoString(MQL_PROGRAM_PATH),   "MQL5",0 ) > -1 ||   TerminalInfoString(TERMINAL_NAME)=="MetaTrader 5" ) MT_version = 5;

}
//if ( MT_version ==5) {}

If you want a variable, you can do it like this:

enum VersionEnum
  {
  MQL4,
  MQL5   
  };

#ifdef __MQL4__
   VersionEnum MT_version = MQL4;
#else  
   VersionEnum MT_version = MQL5;
#endif

// Then in the code you can use this way:
void SomeFunc()
{
  if(MT_Version == MQL5) 
    Print("5");  // Here you do something useful 
}
