Nancy Jacobsen published a solution to this problem in FoxTalk a long, long time ago (1990 or 1991, I think).

The basic idea is that you set up your report with as many columns as fit comfortably. In the calling program, you use code like:

nColumns = # of data columns in the report
nDataFields = FCOUNT() - 1 && first field is label
nPages = INT(nDataFields/nColumn) + 1

FOR nPage = 1 to nPages
REPORT FORM (YourReport)
ENDFOR

In the report, you use a complicated expression involving the FIELD() function and nPages to put the fields (and the headings) in place. It varies from column to column, but it's along these lines (this one is for the first data column):

IIF(TYPE(FIELD((nPage-1)*nColumns + 1)) <> "U", ;
FIELD((nPage-1)*nColumns + 1),"")

IOW, the first time through the loop, you report on data columns 1 through nColumns. The second time, it's nColumns + 2 up to 2*nColumns, etc.

The expression for the data checks whether there's a field to report on in this column and if so, shows the data.

Hope this helps.
