Repeats a group of statements a specified number of times.
for (statement1; statement2; statement3)
statement consists of three parts separated by semicolon:
- Specifies the initial numeric value of the variable used as cycle counter. For example:
- Logical expression that is evaluated ata the beginning of each cycle iteration. If the expression returns true
, then the iteration is completed, otherwise the cycle is exited.
It is usualy a simpe test whether the cycle counter is within the defined range.
i < 20
- This statement is executed at the end of each iteration. It is usualy an incrementation (or decrementation) of corresponding cycle variable. For example:
statement can be used inside a loop to provide an alternate way to exit.
For similar purpose in the VBScript language
is used the statement For...Next
A simple cycle example. It dumps text i=1
into the Debug_info
item of the INFO system.
for (i = 0; i < 2; i++)
Pm.Debug("i=" + i);
You can nest For...Next loops by placing one For...Next loop within another. Give each loop a unique variable name as its counter. The following construction is correct:
var i, j, k;
for (i = 1; i < 3; i++)
for (j = 1; j < 3; j++)
for (k = 1; k < 3; k++)
Pm.Debug("i=" + i + ", j=" + j + ", k=" + k);
