FOR variable = value[, ...] DO statement
Arguments
variable
A variable that is modified before each execution of the loop. (a or n)
value
An expression to be assigned to variable before each execution of statement. All values must be the same data type as variable. (a or n)
statement
A single or compound statement to be repeatedly executed.
Discussion
The FOR-DO statement executes a statement repeatedly until a specified list of values is evaluated.
The first value in the list is assigned to variable before the first execution of the statement, the second value is assigned before the second execution, and so forth. When each value in the list has been assigned, the FOR statement is terminated and control is transferred to the statement following the FOR statement.
Statement can be on the next physical line. It is executed once for each value specified. Statement must execute code; for example, it cannot contain only a label.
The FOR and the DO keywords must always be on the same line. |
Examples
The following example assigns the values 8, 28, 13, 33, and 38 to result elements 1, 5, 2, 6, and 7, respectively.
record v1 ,i2 v2 ,i2 i ,i2 proc v1 = 3 v2 = 5 for i = 1, 5, 2, 6, 7 do result(i) = v2 * i + v1 end
The following example assigns four separate alpha values to a complex manipulation.
record string ,a100 alf ,50a10 len ,i2 maxlen ,i2 result ,a200 proc for string = alf(12), alf(17), alf(22), alf(35) do begin xcall cnvrt(string, len) if (len .gt. maxlen) string(maxlen + 1) = '%' xcall parse(string, result) xcall act(result) end end
