Steps through a procedure one command at a time, halting after each command.

Syntax

Comments

When SINGLESTEP is switched ON, execution is halted (by the HALT utility) after each command executed. To resume execution after the HALT, press Enter at the HALT prompt (>>).

Compiled application programs are not affected by SET SINGLESTEP.

The SET SINGLESTEP command is not affected by the SET RESET and SET RESTORE commands.

Example

To switch to singlestep, use

> set trace on
> set singlestep on

Now, if you execute an application program, it looks like this:

> DoCusts (“edit”)
procedure DoCusts (in ExMode)
>>output $setcount
 35
>>(carriage return)
let dp = $true
>>.
 .
 .
