EAOPT is a set of €ASM options controlled with

1. built-in factory defaults,
2. keywords specified in euroasm.exe command-line,
3. keywords specified in [EUROASM] section of euroasm.ini,
4. keywords specified as operands of pseudoinstruction EUROASM.

Instances of this class appear as member of EA, SRC, PGM and Src.EaoptStack objects.
All EAOPT objects allocate memory from Ea.Pool.

Current Euroasm options in charge, which control the assembly, are always read from Ea.Eaopt.

In order to introduce a new EUROASM option, it must be inserted into

1. %Eaopt*List enumeration,
2. EAOPT structure,
3. factory-default euroasm.ini file,
4. EaoptAssemble configuration handler,
5. VarExpand retrieve handler,
6. Pseudoinstructions/EUROASM manual,
7. Elements/EUROASM System %variables manual,
8. test program.

↑ EAOPT

This structure contains assembled options from configuration file euroasm.ini or from pseudoinstruction PseudoEUROASM. There are five kinds of options in EAOPT, specified in enumerations defined below:

1. %EaoptStatusList enumerates boolean members defined in EAOPT.Status encoding and kept in EAOPT.Status,
2. CPU generation options listed in DictEaoptCpu dictionary declare boolean members in CPU requirements encoding kept in EAOPT.Machine,
3. SIMD generation options listed in DictEaoptSimd dictionary declare boolean members in SIMD requirements encoding kept in EAOPT.Machine,
4. %EaoptFeaList enumerates boolean members defined in CPU features encoding and kept in EAOPT.Features,
5. %EaoptMiscList enumerates miscellanous non-boolean members listed in DictEaoptMisc dictionary and kept in EAOPT members.

↑ EaoptGetOnePath PathPtr, PathSize, PathNr

EaoptGetOnePath returns one of the many pathes which may be specified by Euroasm option INCLUDEPATH= or LINKPATH=.
They may be separated with comma , or semicolon ;.

Input

PathPtr is pointer to the pathstring INCLUDEPATH / LINKPATH, without quotes.
PathSize is number of bytes in this string.
PathNr (0,1,2...) specifies how many pathes to skip in INCLUDEPATH / LINKPATH contents.

Output

CF=0 ESI,ECX specify one path, unquoted, trimmed from white spaces. It may not be terminated with slash.
CF=1, ECX=0 if no path with requested ordinal number is found in INCLUDEPATH / LINKPATH.
