Notes for Users of QUEL
This appendix covers differences between QUEL syntax and 4GL. The differences appear by text chapter, and provide alternative examples written with QUEL syntax.
• In addition to the differences described in this appendix, note that some application development features are not supported in QUEL. QUEL does not support global variables, records, global application constants, or multiple sessions. These are supported for SQL only.
• For QUEL and 4GL reserved words, see
Keywords.
In general, this appendix does not show examples in which the only difference between SQL and QUEL is QUEL's use of double quotes.
