There is a paper called IPDS and SCS Technical Reference:
http://publib.boulder.ibm.com/prsys/pdfs/54453124.pdf
On page 203 there is an explanation whether portrait or
landscape mode has to be used. To decide this, the Page width
and length is calculated as follows:
Characters per line (MPP)
Physical Page Width = ----------------------------
(in inches) Font pitch
(characters per inch, CPI)
Lines per page (MPL)
Physical Page Length = --------------------
(in inches) Lines per inch (LPI)
If you always use the same Font and ignore Font commands
(like SCD, SFG), this should be easy.
Remember that some commands (like SPPS and SHM/SVM) use inch-based
parameters and rely on correct font pitch. They have to be ignored too.
Hope this helps.
