The Xlate$ internal function returns A$ translated using B$ as a translation table. If X is specified, it starts in position X of string A$; otherwise it starts at the first character of A$.
Xlate$(A$,B$[,X])
Comments and Examples
Whenever ASCII character null (CHR$(0)) is found in A$, it is replaced by the first character in B$. ASCII character Ctrl-A (CHR$(1)) is replaced by the second character in B$. In other words, ASCII character N-1 is replaced by the Nth character of B$. ASCII values greater than LEN(B$)-1 are not changed.
00100 LET Y$=XLATE$(X$,TABLE$)
In line 100, Y$ will be a translation of X$ using Table$. For example, spaces (ASCII value 32) will be replaced by Table$(33:33), the character in the 33rd position of Table$.
Related Functions
During input or output operations, data can be translated (for example from ASCII to EBCDIC) by using the TRANSLATE= parameter in the OPEN statement.
