Hi there,

Is there someone who knows how to convert a string in MSX basic to lowercase?

The only thing i could find is: A$=CHR$(ASC(A$) AND &HDF).
But it's the other way around (this converts A$ to uppercase)

Thanks in advance

A$=CHR$(ASC(A$) AND &HDF or 32)

@ assembler: Thank you! Will try that one..

Not working the way i would like...

I would like to see the whole string being converted not only the first character...

Sorry if i wasn't clear Wink

For t=0 to Len(a$)-1
output$=mid(a$,1+t,1) with magical math
Next t

Alternative, just for the fun of it... (but be careful with it):

10 INPUT A$
20 P=VARPTR(A$):L=PEEK(P):AD=PEEK(P+1)+256*PEEK(P+2)
30 FORI=ADTOAD+L:POKEI,PEEK(I)OR32:NEXTI
40 PRINT A$

still, it's a nice demo of VARPTR... Fun fact: if the string is a constant in the program, this code will modify the program itself Smile
This is the way you would do it in C, approximately Smile
