PL/I and type tree mapping

Edit online

PL/I names are converted to type tree names according to the following rules:

  1. Characters that are not valid in type tree element names are replaced with 'x'. For example, monthly$total becomes monthlyxtotal.
  2. Duplicate names are made unique by the addition of one or more numeric digits. For example, two instances of year become year and year1.
PL/I importer maps PL/I data types to type tree elements according to the following table. PL/I types that are not shown in the table are not supported by the importer. The following restrictions also apply:
  • Data items with the COMPLEX, FLOAT, VARYING, and VARYINGZ attributes are not supported.
  • Data items with the FLOAT attribute are supported. PL/I FLOAT IEEE is not supported.
  • VARYING and VARYINGZ pure DBCS strings are supported.
  • Data items that are specified as DECIMAL(p,q) are supported only when p ? q.
  • Data items that are specified as BINARY(p,q) are supported only when q = 0.
  • If the PRECISION attribute is specified for a data item, it is ignored.
  • PICTURE strings are not supported.
  • ORDINAL data items are treated as FIXED BINARY(7) data types.

The following table lists PL/I data types and the corresponding properties and property values in the resulting type tree.
