# accepting uppercase characters and
spaces.
MAJ = toupper(ctrans([F]VILLE))
ENTREE =
sigma(I=32,64,chr$(I))+sigma(I=91,127,chr$(I))
# all printable characters, apart from
upper-case.
MAJ = ctrans (MAJ,ENTREE,space$(127)
# no problem if the output string is too long…
[M]VILLE = vireblc(MAJ,5)
# simply remove excess blanks
# "23020 Saint-Thomas d'Aquîn s/mer" ->
" SAINT THOMAS D AQUIN S MER"
# Same process, but without spaces
[M]VILLE = ctrans (MAJ,ENTREE,"")
# the same string will be
"SAINTTHOMASDAQUINSMER"
ctrans with one argument is used to transform a string of characters into one of the same length but where all the characters are coded over 7 bits. Accented letters (upper or lower case) are changed to non-accented letters, non-printing characters are changed to spaces, and semi-graphics to "+", the – character to "-", and the | character to "!". Other characters remain the same.
ctrans with 3 arguments is used to transform one character
string to another. Each character in the string to be transformed is searched
for in the second string – known as input string. If it does not appear, it
will not be changed. If it appears, its position in the input string is noted
and it is replaced by the character in the third string, the output string,
from the same position. If its position is higher than the length of the output
string, it will not appear in the result.
The result is a Char type.
