// VARIABLE DECLARATION

// legacy syntax
var var1 num 56 static     // types is the same as for 'num' field, may be used for any field
var (var2, num, 45)  		 // type is omitted, "static" type is assumed

// new simple syntax
int i1 = 5
string str1 = 'value'
hex hexnum = 0x78         // will be displayed as hex

printl 'var1=$var1$'
printl 'i1=$i1$'
printl 'str1=$str1$'
printl 'hex=$hexnum$'
hexnum = 1	// 1 is treated as decimal number
printl 'hex=$hexnum$'

// MODIFICATION OF VARIABLES

incvar var1 2
var1 += 4      // is similar to incvar
decvar var1 4
var1 -= 3      // is similar to decvar

var1 = 10000000
mulvar var1 3
divvar var1 2
print '$var1$\n'

// STROING IN FILES

STRING v3 = "to save in file" // another way to declare variable

// writing and reading from file
writevar v3 'file_with_var'
loadvar v3 'file_with_var'
printl v3

// CONVERT INT TO STRING

string s1 = ''
s1 = '$i1$'
printl s1

// USING VARIABLES AS VALUES TO COMMANDS

INCLUDE tcp

var1 = 777777
ack = var1        // initialization field by variable
print 'ack=$ack$\n'

// USING AUTOSET VARIABLES
