- Hypens (dashes) within record and item names are changed to underlines.
- All common items in IMPS are changed to ID items in CSPro.
- As CSPro does not allow the use of subitems in the ID section, any subitems found in the IMPS common section will be converted to ID items. This could increase the length of the ID section. Therefore we advise you to check your CSPro dictionary after conversion if you receive a message about "subitems found in common, promoted to ID items". Similarly, if you receive any error messages during the conversion about overlapping items, this is most likely due to the use of subitems in the common block of IMPS.
- If you have used "NR" as a value name in your IMPS dictionary, it will be converted to the special value missing.
- If you have used "NA" as a value name in your IMPS dictionary, it will be converted to the special value notappl.
- All hierarchy information is lost.
- All other comments as listed under IMPS 3.1 to CSPro apply.
- Underlines within record and item names are changed to hyphens (dashes).
- All level record, item, and value set labels are lost.
- All value labels are truncated to 16 characters.
- Value sets, after the first, are converted to subitems.
- All notes are lost.
- All level information is lost.
- All special values (missing, refused, notappl, and default) are lost.
CSPro allows the use of long names even though IMPS only allows 16 characters. Therefore, if any of your unique names are longer than 16 characters, you will receive a message for each variable that its name will be truncated to 16.
CSPro does not support the use of short names, as described in IMPS. Therefore, if the first 8 characters of any item name in CSPro are not unique, the converted IMPS dictionary will have duplicate shorts names. You should check the converted IMPS dictionary to ensure that there are no duplicate short names.
