When is a string not a string

[Shane Dewitt]

VEHU>S X="12E1234567890"

VEHU>I X W 1
%YDB-E-NUMOFLOW, Numeric overflow

VEHU>I +X W 1
%YDB-E-NUMOFLOW, Numeric overflow

VEHU>S X="12e1234567890"

VEHU>I X W 1
1
VEHU>I +X W 1
1
VEHU>

See https://groups.google.com/g/comp.lang.mumps/c/nTAC4300T1E/m/OVhC3BpoCAAJ for the answer. Use follows (]]) against $char(0) or space (" ").

but I believe you are concerned about the exponent uppercase E returning NUMOVERFLOW... 

Sorry, but I have no idea about it...

Nikolay fixed the code. I think the NOT Equal keeps X as a string so it does not overflow.

VEHU>S X="12E1234567890"

VEHU>I X'="" W 1
1

[Stefano Lalli]

if $ztranslate(x,"E","e") bla bla bla

just an idea...

I really don't want to change X or the code that checks X. I was hoping there was a flag or setting I could set that would not coerce strings with E in them to a scientific notation.

Thanks.
