You can use the unhold command to control which UDFs run when continue commands are entered. Threads that are held will not execute; all others will execute.

Syntax

unhold all
unhold thread-selector [...]

Syntax Elements

thread-selector
Specifies a string that selects one or more UDF threads being debugged.

Usage Notes

You can use hold and unhold together. For example, you could use hold all and then unhold just the thread you want to execute.

This affects only the continue command; the step and next commands implicitly hold all threads except the current one.
