EZT: Using an indexed field as a KEY on the JOB INPUT statement and getting a compile error EZTC0062E. What causes this?

Products

• Easytrieve Report Generator

Issue/Introduction

The following will produce an Easytrieve Compile error:

          1  FILE PERSNL VS
                  2  REC150              001  150 A  INDEX REC150-IDX
                  3  EMPNUM   REC150    +009  005 A
                  4  *
                  5  JOB INPUT (PERSNL KEY EMPNUM)
EZTC0062E >>>                        $ cannot be an INDEXed field
                  6       DISPLAY EMPNUM

 

 

Environment

Easytrieve Report Generator, release 11.6

Resolution

With Easytrieve r11.6, additional error logic was added to ensure a key field can't be varying, indexed, or subscripted.

The following is why the additional error checking was added to the Easytrieve r11.6 compiler:

• For the JOB INPUT (filename KEY key-fieldname) statement, using an indexed field could cause errors and/or improper references
• The key-fieldname may not be referenced from the same location in the record, when looping back to the JOB statement for the next record, producing inconsistent results.
