loop

  The loop command repeatedly executes any LaGriT command with either a do loop type or foreach type variable argument control.

The coomand supports loops up to 10 deep with a maximum of 250 tokens in the foreach list.

SYNTAX

loop/ do / variable / loop_start / loop_stop / loop_stride/ loop_end / LaGriT_command

loop/ foreach / variable / list_var1 list_var2 ...
 list_varN / loop_end / LaGriT_command

do or foreach are keywords that determine the type of loop operation.

variable is a character string that can be used in the LaGriT_command. The variable values are controled by the loop range or given in a variable list.

loop_start / loop_stop / loop_stride Integers that specify the initial, limit, and increment of variable.

variable / list_var1 list_var2 … list_varN Integers, reals or characters that are substituted into variable prior to each execution of the LaGriT_command.

loop_end Required keyword string to terminate a foreach list. It is also REQUIRED after loop_stride.

LaGriT_command Any valid LaGriT command including another loop command.
