Hmmmmm, lets see, in rough chronological (that's my long word for the day!) order:

ZX Spectrum Basic,
Assembly on ZX Spectrum (well, I got it to print my name!)
STOS Basic on Atari ST,
GFA Basic, again on Atari ST,
Pascal also on Atari ST,
some sort of BASIC on DOS, might be GWBasic?
Paradox,
DBase,
Paradox,
FoxPro,
Delphi,
VB Dos,
VB 3, 4, 5, 6 & .NET
VBA,
HTML,
JavaScript (also my least favourite)
ASP,
Perl,
And a very quick dabble with C/C++ at various stages,
and an even briefer look at PHP

Also SQL, MySQL as others have put that down.
Can I include DOS batch files? Done a few big clever ones in my time.
