Brittani,
I would use one of the versions of the manual here:
https://www.gnu.org/software/pspp/manual/
such as this one:
https://www.gnu.org/software/pspp/manual/html_node/index.html
or the PDF version:
https://www.gnu.org/software/pspp/manual/pspp.pdf
PSPP has capabilities, like GLM, that the graphical interface
doesn't express (this is also true of SPSS; for example, one cannot
access MANOVA from the GUI). But you can use syntax to perform a GLM
analysis, as described here:
https://www.gnu.org/software/pspp/manual/html_node/GLM.html#GLM
The GLM command doesn't have any explicit support for ANCOVA and
I've never used GLM to perform the analysis, but these links suggest
that you're correct that it's possible:
http://www.theanalysisfactor.com/general-linear-model-anova-regression-same-model/
http://stats.stackexchange.com/questions/21229/difference-between-ancova-and-hierarchical-regression
Let us know if you have difficulty or questions using the syntax for
your analysis. If you do have problems, please identify the
platform (Windows, MacOS, etc.) and version (from Help > About)
that you are using. PSPP just releases a new version, 0.10.0, but
aside from various small improvements, I don't think it affects what
you are doing.

I've... seen things you people wouldn't believe...
functions on fire in a copy of Orion.
I watched C-Sharp glitter in the dark near a programmable gate.
All those moments will be lost in time, like Ruby... on... Rails... Time for Pi.
