NAME
show - to allow for tracking of the access to specific variables in message sequence charts.

SYNTAX
show typename name

DESCRIPTION
This keyword has no semantic content, but only serves to determine which variables should be tracked and included in message sequence chart displays. The value of all variables of which the declaration is prefixed with the keyword show is updated on a separate time-line in these displays.

NOTES
The use of this prefix only affects the information that Xspin includes in message sequence charts, and the information that Spin includes in Postscript versions of message sequence charts under Spin option -M .
