*
* DBD::Informix for Perl Version 5 -- Test Informix-ESQL/C environment
*
* This is a stripped down version of the esqltest.ec program, but it is
* a pure ESQL/C program which is completely self-contained (it does not
* require any source or headers other than those which come with ESQL/C).
* Used when people really run into problems. Compile using the following
* command line (ensuring that there is no esql script modified by
* DBD::Informix in the way of the official esql script):
*
* esql -o esqlbasic esqlbasic.ec
*
