Source

The Source window is somewhat similar to the macro trace window, except that the entire macro source is shown, with a marker identifying the line about to be processed. The source window also shows the CL file source, both in its original APT format (if applicable) as well as its transformed binary format. Any macro can be examined in the window, regardless if active or not. Four buttons in the Source window single-step through the macro or CL file in various ways.

Step into: Processes the current record (either macro or CL), stopping at the very next record (again, either macro or CL). If the current record matches a macro, then Step-in will stop at the first executable line of the matched macro. If the current record does not match a macro, then Step-in acts the same as Step-over.
Step over: Processes the current record (either macro or CL), stopping at the next record of the same macro or CL file. Unlike Step-in, if the current record matches a macro, then Step-over will not stop in the matched macro.
Step out: This is applicable when stepping inside a macro. Step-out continues processing past the last record of the current macro. After Step-out, processing will be paused at the next record to processed by the caller (either a macro or CL).
Run to cursor: Continues processing to the selected macro line or CLDATA record. Select the macro line or CLDATA record first, before selecting the “Run to cursor” feature.
Go to line: Use the edit box to enter a line number you want to go at and then press the Goto button next to it.
A drop down list showing all sources that can be look at. This includes the CL source file as well as any macros defined inside the post-processor.

When looking at the CL source, the popup context menu (right mouse button click) will give you the choice to look at the ASCII version (only if the CL source is one of the ASCII source accepted by GENER) or at the internal binary version of the CL file.

You can set or remove a break point by clicking in the margin next to the line where you want to set or remove a break point. You can also use the context popup menu to set/remove or toggle breakpoints. The number of lines visible inside the Source window can be set from the tool setup options dialog. Leaving your mouse over a variable name will bring up a tooltip window listing the current value of that variable.
