Expressions and Functions

Example:

ss = "3 pieces 2x5 beam"

n = SPLIT (ss, "%n pieces %nx%n %s", num, ss1, size1, ss2, size2, name)

PRINT "ERROR"

ENDIF

STW

STW (string_expression)

Returns the (real) width of the string in meters displayed in the current style. The width in meters, at current scale, is STW (string_expression) / 1000 * A_.

Example:

DEFINE STYLE "own" "Monaco", 180000 / A_, 1, 0 SET STYLE "own"

string = "abcd"

width = STW (string) / 1000 * A_

n = REQUEST ("Height_of_style", "own", height) height = height / 1000 * A_

text2 0,0, string

rect2 0,0, width, -height

STRLEN

STRLEN (string_expression)

Returns the (integer) length of the string (the number of characters)

STRSTR

STRSTR (string_expression1, string_expression2)

Returns the (integer) position of the first appearence of the second string in the first string. If the first string doesn’t contain the second one, the function returns 0.

Expressions and Functions

STRSUB

STRSUB (string_expression, start_position, characters_number)

Returns a substring of the string parameter that begins at the position given by the start_position parameter and its length is characters_number characters.

Example:

ss = ""

n = REQUEST ("Linear_dimension", "",ss) unit = ""

IF STRSTR (ss, "m") > 0 THEN unit = "m" IF STRSTR (ss, "mm") > 0 THEN unit = "mm" IF STRSTR (ss, "cm") > 0 THEN unit = "cm"

TEXT2 0, 0, STR (ss, a) + " " + unit !1.00 m string = "Flowers.PICT"

len = STRLEN (string)

n = STRSTR (string, ".")

TEXT2 0, -1, STRSUB (string, 1, n - 1) !Flowers TEXT2 0, -2, STRSUB (string, len - 4, 5) !.PICT
