Data Set or cell references

Always enclose set references and ODBC cell references in square brackets. This avoids ambiguity and is easier to read. For example:

[*set NewIndex=[dsMine.ThisOne]]

…to get the value from the data set.

Always enclose file, worksheet and column names in quotes even if they do not contain spaces:

[*dbopen dfExcel=’MyFile.xls’]

[*dbloop dlThisRow = dfExcel;’Sheet1’;’Value’,’Name’]

 

[*dbopen dfAcc=’MyFile.bdb’]

[*dbloop dlRow = dfAcc;’Questions’]

Text in PP code

Always enclose text within single quotes if you want to treat it as text.

When the text in an index is referred to, always use @ to make sure that the exact text is used. For example:

[*set NewIndex=’[@MyText]’]

…to get the text from the index.

When the text in a data set is referred to always enclose in quotes. For example:

[*set NewIndex=’[dsMine.ThisOne]’]

…to get the text from the data set.

Lookup in ODBC

To use a database as a lookup table use [*DBFINDROW] and [*LAST], for example:

[*dbfindrow FoundRow = dfFile;’Sheet1’;’Response’=’NA’]

[*dbloop dlFoundRow = (FoundRow)dfFile;’Sheet1’]

[*last dlFoundRow]

[*set FoundText = dlFoundRow.’Text’]

[*dbend dlFoundRow]
