What should the output be for the input:
Code:
@LIB ADVAPI32.dll @CAL RtlInitAnsiString @PA1 0x0012f740 @PA2 "CriticalSectionTimeout" @RET0 
@LIB ADVAPI32.dll @CAL RtlInitAnsiString @PA1 0x0012f740 @PA2 "CriticalSectionTimeout" @RET0 
@LIB ADVAPI32.dll @CAL BlaCall @PA1 0x0012f741 @PA2 0x0012f68c @PA3 4 @RET 0x0012f8bc 
@LIB ADVAPI32.dll @CAL memmove @PA1 0x0012f740 @PA2 0x0012f68c @PA3 4 @RET 0x0012f8bc 
@LIB ADVAPI32.dll @CAL RtlAnsiStringToUnicodeString @PA1 0x7ffdfbf8 @PA2 0x0012f740 @PA3 FALSE @RET STATUS_SUCCESS

(which is your sample input file with line 2 removed)? Is line 1 kept in the output as is, or should lines 1 through 4 be changed to a single:
Code:
@MATCH

output line?

What should happen if there are more than 3 newlines between @CAL RtlAnsiStringToUnicodeString and @CAL memmove if there are no other occurrences of @CAL RtlAnsiStringToUnicodeString between them?

NAME
convickt - convert INTERCAL files between formats SYNOPSIS
convickt incharset outcharset [paddingrule [arrayname]] DESCRIPTION
This manual page describes the convickt command. Fuller documentation is available via the command info convickt convickt converts INTERCAL programs from one character set to another; it takes input from standard input and sends its output to standard output. OPTIONS
For incharset and outcharset atari Interpret the input as being ASCII-7 Atari syntax INTERCAL, as is used by the Atari INTERCAL-72 compiler, J-INTERCAL, and C-INTERCAL default syntax, or output in that syntax. baudot Interpret the input as being in CLC-INTERCAL's extended Baudot syntax, or output in that syntax. ebcdic Interpret the input as being in the CLC-INTERCAL dialect of EBCDIC, or output in that syntax. latin1 Interpret the input as being Latin-1 Princeton syntax INTERCAL, as is used by default by CLC-INTERCAL and also readable by C-INTER- CAL with the -X switch, or output in that syntax. For paddingrule zero Pad the irrelevant bits in ASCII-7 and Baudot output with zeros. printable Set the values of the irrelevant bits in ASCII-7 and Baudot output to try to cause the output to stay within character range 32-126. This option is the default. (Note that paddingrule is irrelevant for 8-bit character sets like Latin-1 and EBCDIC). random Pad the irrelevant bits in ASCII-7 and Baudot output with random data, except that outputing an all-bits-zero octet is avoided. CAVEATS
Not all conversions are possible, due to the character sets having different characters available. In most cases, an unconvertible or invalid character will be converted to a 0 (padded appropriately); the exception is that if a tab cannot be converted, it will instead be converted to a single space (so that INTERCAL programs still run if converted to Baudot). Using atari as an input or output character set will literally convert characters which differ between Atari and Princeton syntax without checking to see whether they are being used as operators or not. If arrayname is given, then instead of outputting the converted text literally, it will be output as portable (that is, legal in INTER- CAL-72, C-INTERCAL, J-INTERCAL and CLC-INTERCAL) INTERCAL that dimensions the tail array given as arrayname and assigns each byte of the output to an element of that array; this is mostly useful for producing Baudot text for CLC-INTERCAL-style array IO.
