# for x

Description:

Start a loop.

Syntax:

for  x

Note:

The statement starts a loop executing the code block.

Parameter:

 x A sequence, an integer, or a logic expression. Loop through the code block against x or to(x), or if x is true. If x is empty, then the loop will be endless.

Example:

x is an integer:

 A B 1 Save the cumulative total 55 in A1 2 for 10 3 >A1=A1+A2 Add up the integers from 1 to 10

x is empty:

 A B C 1 =0 5050 2 for Loop will be endless if x is empty. When the loop count reaches 100, then break the loop 3 >A1=A1+#A2 4 if #A2==100 break

x is a boolean expression:

 A B 1 =15 2 for A1>10 If A1 >10, then start a loop through the code block; otherwise, quit the loop 3 >B1=B1+#A2 4 >A1=A1-1

x is a sequence:

 A B 1 =demo.query("select * from EMPLOYEE") 0 Get the oldest age among all Texas employees in B1 after the loop is over 2 =A1.select(STATE=="Texas") 3 for A2 =age(A3.BIRTHDAY) A3 performs loop over each Texas employee while computing their age 4 >B1=max(B1,B3) The oldest age is stored in B1
