step

Continues running the program by executing the next line of source code, and then stops.

Syntax

s[tep] [count]
  1. count defines the number of lines to execute before stopping.

Usage

The step command allows you to "step" through your program executing one line of source code at a time. When a function call appears within the line of code, that function is also stepped through.

A common technique is to set a breakpoint prior to the section or function that is causing problems, run the program until it reaches the breakpoint, and then step through it line by line.

Example

(fgldb) step
4 call addlist(a)
(fgldb)
Important: The step command cannot be used to step through a function that was compiled without debugging information. Execution continues until it reaches a function that does have debugging information.
