A. System considerationsConsider the following items when designing and planning yourform:• Line density limits• Local density limits• Superimposed edges when adjoining boxes• Text size in boxes• Lines with sections.These items are especially important when designing complexforms. You can avoid error messages and save the time it takesto correct the problems by being aware of the systemconsiderations described in this appendix.Line density limitsThere is a limit to the number of characters and lines you canimage on a page. The basic limit is measured in units calleddispatchable items.A dispatchable item has a maximum of 32 dots and can be thefollowing:• Full character—of point size 8, 9 or less• Fraction of a character—greater than point size 8 or 9• Line segment—equal to or smaller than 32 dots in the scandirection.Local density and page setup errorsYou may encounter a page setup error while the printer isimaging a page. This error indicates there was not enough timefor the printer to image a page. One of the following conditionsmay have caused the problem:• Excessive amount of data to be imaged• Disk errors• Imaging problems• Local density problem.If you design a form to avoid exceeding line density limitations,you may cause page setup errors because of local density. Longlines of small text set with close spacing cause a local densityproblem. The imaging hardware accepts and dispatchescharacters at two different rates. If the form structure imposestoo heavy a dispatchable load, the hardware may run out of inputbefore all of the data has been processed. You rarely encounterthis problem in readable forms.HOST FORMS DESCRIPTION LANGUAGE 3.2 FOR IBM MVS CREATING FORMS A–1
