Specification=S...W...

S or s is the starting column in the person or item label

W or w is the width in columns

E or e is the ending column in the label

- indicates the column range

DPF=$S1W1

DPF=S1W1

DPF=1W1

DPF=1

means "use the section of the item (or person) label starting in column 1 of the label with a width of 1 column".

DPF=$S3W2

DPF=S3W2

DPF=3W2

means "use the section of the item (or person) label starting in column 3 of the label with a width of 2 columns".

DPF=$S3E4

DPF=S3E4

DPF=3E4

DPF=3-4

means "use the section of the item (or person) label starting in column 3 of the label and ending in column 4".

Specification=C...W...

Specification=C...E...

Specification=c...w...

Specification=c...e...

C or c is the starting column in the item label or person data record

W or w is the width in columns

E or e is the ending column in the data record

This always works if the columns are within the person or item label. If the columns referenced are in the data record, but outside the person label, the information may not be available.

PWEIGHT = $C203W10

PWEIGHT = C203W10

PWEIGHT = C203E212

means "person weighting is in column 203 of the data record, with a width of 10 columns, ending in column 212"

Specification=N

the person or item entry number is displayed

Specification = @Fieldname

selects one or a block of columns as specified by a prior @Fieldname= instruction

@AGE = 2E3

PSUBTOTAL = @AGE

the person's age is in columns 2 and 3 of the person label:

subtotal the persons by age classifier

Specification=MA3

Specification=MD2

M = Measure

A = Ascending or D = Descending

1 or higher integer: number of strata

 e.g., MA3 = Measures Ascending in 3 ability strata

Specification=FOMA3

Specification=FILD4

F = Fit, I = Infit, O = Outfit

M = Mean-square, L = Log-mean-square, S = t Standardized

A = Ascending or D = Descending

1 or higher integer: number of strata

 e.g., FILD2 = Fit - Infit - Log-scaled - Descending -2 fit strata

Strata

Stratum for this value = Max(1+ Number of strata * (Current value - Lowest)/(Highest -- Lowest), Number of strata)

where Lowest is the most negative value observed and Highest is the most positive value observed.

DIF=MA3

Specification = selection + selection

+ signs can be used to concatenate selections

IMAP = 3-4 + 8W3

show in Table 12 columns 3, 4, 8, 9, 10 of the item label.

Specification = "..."

Specification = '...'

constants in quotes can be included with selection.

PMAP = 3 + "/" + 6

show in Table 15 column 3, a slash, and column 6 of the person label, e.g., F/3

Multiple-format specifications:

IAFILE=value, PAFILE=value, etc.,

value is first checked for "*", which precedes a list. If not this,

it is parsed as a selection. If not a valid selection,

it is parsed as a file name.

Consequently, a mis-specified selection may produce a "file not found" error.
