fScan internal variables

fScan supports several different types of internal variables. Values of some variables are global – they do not change when you move from one active window to another. Other variables are workspace or data set specific – their values will change depending on which window is currently active.

Accessing data variables

In general, data variable values can be accessed by specifying the name of the variable, preceded by the'$' character. For example:

echo Window: $thiswin WorkSpace $wsnum ; display name of current active window

thiswin	The name of the current window
prevwin	The name of the previous window
thispdigm	The name of the current pdigm file
thisevents	The name of the current events
subjectname	The name of the current subject
subjectdir	The name of the current subject directory
curdir	The current working directory
