Conversion Utilities

This section outlines the steps required to convert an existing Thoroughbred® application to PxPlus. The toolkit described herein is located in the *conv.tbd directory and consists of a number of programs, which convert the programs and data files.

Note:
The *conv.tbd directory will be found in the lib directory where PxPlus was installed along with the various other system utilities, the system will replace the asterisks ( * ) with underscores ( _ ). For the purposes of this documentation, it is assumed that PxPlus has been installed in /pxplus thus *conv.tbd will be in /pxplus/lib/_conv.tbd.

This section covers the following topics:

IPLINPUT and TERMINAL File Conversion

FINPUT Emulation

The following system parameters setting should be reviewed when running converted programs:

• System parameter '47' that emulates the error 47 suppression logic found in Thoroughbred®
• Options to have CLOSE (0) close all files when the system parameter 'FF' (FID Format) is set to Thoroughbred® emulation
• System parameter '+5' forces line numbers to be output as five digits for compatibility

A few additional PxPlus specific features can also help:

• The DROP directive allows either the original program name (as supplied on the ADDR directive) or absolute pathname as given in the PUB function
• The INPUT directive allows for the inclusion of both simple string variables in a validation list for an input

Example:

INPUT @(5,5),X$:(YES$ =1000, NO$ =2000)
