-====== String Equations ====== 
- 
-Topas v6 includes string equations. ​ Some examples: 
- 
-<code topas> ​               out_file ​ aac.out ​ ‘ This will throw an exception 
-                out_file = aac.out; ‘  This will throw an exception 
-                out_file = "​aac.out";​ 
-                out_file = String(aac.out);​ 
-                out_file = If(Get(r_wp) < 10, "​aac.out",​ ""​);​ 
-                out_file = If(Get(r_wp) < 10, Concat(String(INP_File),​ "​.OUT"​),​ ""​);​ </​code>​ 
- 
-Some new string handling features are: 
- 
-<code topas> ​               prm aabb = 1.234; 
-                prm sasb = 4.321; 
-                prm sa = "​aa";​ 
-                prm sb = "​bb";​ 
-                prm sc = sb; 
-                prm = Variable_Name_From_String(Concat(sa,​ sc)); :  1.23400` 
-                prm = Variable_Name_From_String(Concat(String(sa),​ String(sb)));​ :  4.32100` </​code>​ 
- 
-String and Variable_Name_From_String are new functions.
