set

Set the value of a variable. This is equivalent to the '=' assignment operator in C/C++.

varref set <varref:var> <variant:VarValue>

NULL if an error occurred, and a valid variable reference otherwise (same as var argument).

int i
set i 50

string s
set s "hello"

float f     // create a float 'f', and initialise
set f 123.456

string s    // create a string 's'
set s f         // set the value of 's' to be 'f' (this is like 'sprintf(s, "%f", f)' in C)

echo s  // echo value of string to event log

… the output of which is written to the event log by echo as:

123.456

int i

set i <zs:GetLineNo> // set value of 'i' to be current line number (i.e. 2)

echo i

… the output of which is written to the event log by echo as:

2

None.
